    The goals of tolerance in patients with solid organ transplants are to eliminate the lifelong need for immunosuppressive (IS) drugs and to prevent graft loss due to rejection or drug toxicity. Tolerance with complete withdrawal of IS drugs has been achieved in recipients of HLA-matched and mismatched living donor kidney transplants in 3 medical centers using hematopoietic cell transplants to establish mixed or complete chimerism.

    Bacterial infections are the most common infections in solid organ transplant recipients. These infections occur mainly in the first month after transplantation and are hospital-acquired. Nosocomial infections cause significant morbidity and are the most common cause of mortality in this early period of transplantation. These infections are caused by multi-drug resistant (MDR) microorganisms, mainly Gram-negative enterobacteria, non-fermentative Gram-negative bacilli, enterococci, and staphylococci. The patients at risk of developing nosocomial bacterial infections are those previously colonized with MDR bacteria while on the transplant waiting list. Intravascular catheters, the urinary tract, the lungs, and surgical wounds are the most frequent sources of infection. Preventive measures are the same as those applied in non-immunocompromised, hospitalized patients except in patients at high risk for developing fungal infection. These patients need antifungal therapy during their hospitalization, and for preventing some bacterial infections in the early transplant period, patients need vaccinations on the waiting list according to the current recommendations. Although morbidity and mortality related to infectious diseases have decreased during the last few years in haematopoietic stem cell transplant recipients, they are still one of the most important complications in this population. Furthermore, as occurs in the general population, the incidence of nosocomial infections has increased during the different phases of transplantation. It is difficult to establish general preventive measures in these patients, as there are many risk factors conditioning these infections. Firstly, they undergo multiple antibiotic treatments and interventions; secondly, there is a wide variability in the degree of neutropenia and immunosuppression among patients, and finally they combine hospital and home stay during the transplant process. However, some simple measures could be

    Transplantation of circulating progenitor/stem cells collected before and stored during administration of marrow-ablative antitumor therapy has restored sustained hematopoiesis for patients with a variety of malignancies. One of the most common diseases so treated is refractory or relapsed non-Hodgkin's lymphoma (NHL). Autologous peripheral stem cell transplantation (PSCT) often has been used rather than autologous bone marrow transplantation (ABMT) because NHL commonly involves the bone marrow, and because, in some situations, PSCT provides earlier engraftment than ABMT. Between July 1986 and September 1992, 170 adult patients with refractory or relapsed NHL were treated with high-dose therapy and PSCT at the University of Nebraska Medical Center (UNMC). With a median follow-up of 469 days for the evaluable survivors, the actuarial progression-free survival for 167 patients at 6 years after PSCT was 30%. High-dose therapy and PSCT for NHL patients has resulted in long-term progression-free survival and probably cure for some patients. The role of PSCT in this disease continues to evolve.

    Allogeneic stem cell transplantation (alloSCT) represents a curative therapeutic option for patients with myelodysplastic syndrome (MDS), but relapse and non-relapse mortality (NRM) limit treatment efficacy. Based on our previous observation in acute myeloid leukemia we investigated the impact of pre-transplant weight loss on post-transplant outcome in MDS patients. A total of 111 patients diagnosed with MDS according to WHO criteria transplanted between 2000 and 2012 in three different transplant centers were included into the analysis. Data on weight loss were collected from medical records prior to conditioning therapy and 3-6 months earlier. Patient, disease and transplant characteristics did not differ between patients with weight loss (2-5%, n = 17; > 5%, n = 17) and those without (n = 77). In a mixed effect model, weight loss was associated with higher risk MDS (p = 0.046). In multivariable analyses, pre-transplant weight loss exceeding 5% was associated with a higher incidence of relapse (p transplant weight loss of 2-5% and > 5% were independent predictors of worse disease-free (p = 0.023 and p transplantation. Prospective studies addressing pre-transplant nutritional interventions are highly warranted.

    We present a case of severe Clostridium difficile infection (CDI) in a non-neutropenic allogeneic hematopoietic stem cell transplant recipient who was treated successfully with fecal microbiota therapy after standard pharmacologic therapy had failed. Following naso-jejunal instillation of donor stool, the patient's symptoms resolved within 48 h. Bowel resection was averted. This is the first case in the literature, to our knowledge, to describe fecal microbiota therapy in a profoundly immunocompromised host with severe CDI. We propose that fecal microbiota therapy be considered as a therapeutic option in immunosuppressed patients with refractory severe CDI.

    Objective: To study the efficacy and safety of autologous transplantation of bone marrow mesenchymal stem cells on diabetic patients with lower limb ischemia. Methods: Fifty Type 2 diabetic patients with lower limb ischemia were enrolled and randomized to either transplanted group or control group. Patients in both group received the same conventional treatment. Meanwhile, 20 ml bone marrow from each transplanted patient were collected, and the mesenchymal stem cells were separated by density gradient centrifugation and cultured in the medium with autologous serum. After three-weeks adherent culture in vitro, 7.32×108-5.61×109 mesenchymal stern cells were harvested and transplanted by multiple intramuscular and hypodermic injections into the impaired lower limbs. Results: At the end of 12-week follow-up, 5 patients were excluded from this study because of clinical worsening or failure of cell culture. Main ischemic symptoms, including rest pain and intermittent claudication, were improved significantly in transplanted patients. The ulcer healing rate of the transplanted group (15 of 18, 83.33%) was significantly higher than that of the control group (9 of 20, 45.00%, P=0.012).The mean of resting ankle-brachial index (ABI) in transplanted group significantly was increased from 0.61±0.09 to 0.74±0.11 (P<0.001). Magnetic resonance angiography (MRA) demonstrated that there were more patients whose score of new vessels exceeded or equaled to 2 in the transplant patients (11 of 15) than in control patients (2 of 14, P=0.001). Lower limb amputation rate was significantly lower in transplanted group than in the control group (P=0.040). No adverse effects was observed in transplanted group. Conclusion: These results indicate that the autologous transplantation of bone marrow mesenehymal stem cells relieves critical lower limb ischemia and promotes ulcers healing in Type 2 diabetic patients.

    Full Text Available Islet cell transplantation offers a potential cure for type 1 diabetes, but it is challenged by insufficient donor tissue and side effects of current immunosuppressive drugs. Therefore, alternative sources of insulin-producing cells and isletfriendly immunosuppression are required to increase the efficiency and safety of this procedure. Beta cells can be transdifferentiated from precursors or another heterologous (non-beta-cell source. Recent advances in beta cell regeneration from somatic cells such as fibroblasts could circumvent the usage of immunosuppressive drugs. Therefore, generation of patient-specific beta cells provides the potential of an evolutionary treatment for patients with diabetes.

    Full Text Available Monica Bhatia,1 Sujit Sheth21Division of Pediatric Hematology/Oncology/Stem Cell Transplantation, Columbia University Medical Center, 2Division of Pediatric Hematology and Oncology, Weill Cornell Medical College, New York, NY, USAAbstract: Hematopoietic stem cell transplantation remains the only curative treatment currently in use for patients with sickle cell disease (SCD. The first successful hematopoietic stem cell transplantation was performed in 1984. To date, approximately 1,200 transplants have been reported. Given the high prevalence of this disorder in Africa, and its emergence in the developed world through immigration, this number is relatively small. There are many reasons for this; primary among them are the availability of a donor, the risks associated with this complex procedure, and the cost and availability of resources in the developing world. Of these, it is fair to say that the risks associated with the procedure have steadily decreased to the point where, if currently performed in a center with experience using a matched sibling donor, overall survival is close to 100% and event-free survival is over 90%. While there is little controversy around offering hematopoietic stem cell transplantation to symptomatic SCD patients with a matched sibling donor, there is much debate surrounding the use of this modality in “less severe” patients. An overview of the current state of our understanding of the pathology and treatment of SCD is important to show that our current strategy is not having the desired impact on survival of homozygous SCD patients, and should be changed to significantly impact the small proportion of these patients who have matched siblings and could be cured, especially those without overt clinical manifestations. Both patient families and providers must be made to understand the progressive nature of SCD, and should be encouraged to screen full siblings of patients with homozygous SCD for their potential to

    Full Text Available Paroxysmal nocturnal hemoglobinuria (PNH is characterized by the triad of intravascular hemolysis, venous thrombosis, and cytopenia. Treatment of PNH is generally supportive. Bone marrow transplantation is the only curative therapy for PNH, but is associated with significant morbidity and mortality. Herein, we present a patient with PNH that received eculizumab, a humanized monoclonal antibody that blocks activation of the terminal complement at C5, before and immediately following allogeneic peripheral stem cell transplantation. Prior to hematopoietic stem cell transplantation eculizumab treatment markedly reduced hemolysis and transfusion requirement; however, 1 d post transplantation a hemolytic episode occured, which was successfully stopped with eculizumab re-treatment. Afterwards the patient did not require additional transfusions. The results of this study indicate that early administration of eculizumab may be a safe and effective therapy for hemolytic episodes associated with allogeneic peripheral stem cell transplantation in patients with PNH.

    Patients who relapse after an autologous hematopoietic stem cell transplantation (SCT) have a very poor prognosis. We have retrospectively analyzed diffuse large B cell lymphoma patients who underwent an allo-SCT after an auto-SCT relapse reported in the Gruppo Italiano Trapianto di Midollo Osseo (GITMO) database. From 1995 to 2008, 3449 autologous transplants were reported in the GITMO database. Eight hundred eighty-four patients relapsed or progressed after transplant; 165 patients, 19% of the relapsed patients, were treated with allo-transplant. The stem cell donor was related to the patient in 108 cases. A reduced intensity conditioning regimen was used in 116. After allo-SCT, 72 patients (43%) obtained a complete response and 9 obtained a partial response with an overall response rate of 49%; 84 patients (51%) experienced rapid progression of disease. Ninety-one patients died, 45 due to disease and 46 due to treatment-related mortality. Acute graft-versus-host disease was recorded in 57 patients and a chronic GvHD in 38 patients. With a median follow-up of 24 months (2-144) after allo, overall survival (OS) was 39%, and after a median of 21 months (2-138) after allo, progression-free survival (PFS) was 32%. Multivariate analysis indicated that the only factors affecting OS were status at allo-SCT, and those affecting PFS were status at allo-SCT and stem cell donor. This retrospective analysis shows that about one-fifth of patients with diffuse large B cell lymphoma who experience relapse after autologous transplantation may be treated with allogeneic transplantation. Moreover, the only parameter affecting either OS or PFS was the response status at the time of allo-SCT.

    Full Text Available Sickle Cell Anaemia (SCA is the most common inherited blood disorder and is associated with severe morbidity and decreased survival. Allogeneic Haematopoietic Stem Cell Transplantation (HSCT is the only curative approach. Nevertheless the decision to perform a marrow transplant includes the risk of major complications  and mortality transplant related. The infections represent the main cause of mortality for SCA patients undergoing transplant. Invasive Pulmonary Aspergillosis (IPA is a devastating opportunistic infection and remains a significant cause of morbidity and mortality in HSCT recipients. Data regarding IPA in the setting of SCA are lacking. In the present report,  we describe a patient with SCA who developed IPA after allogeneic bone marrow transplant. The fungal infection was treated by systemic antifungal therapy in addition to the surgery, despite  mild chronic GVHD and with continuing immunosuppression therapy. This case shows that IPA occurring in bone marrow recipient with SCA can be successful treated

    Objective. To study thymus-dependent T cell development and T cell repertoire in human sever combined immunodeficiency (SCID) patients after HLA-identical or haploidentical T cell-depleted allogeneic bone marrow transplantation (BMT). Methods. Blood samples were obtained from 15 SCID patients before transplantation and at varying intervals thereafter. Quantitative competitive PCR assay and immunoscope analysis of the T cell receptor (TCR) Vβ repertoire were performed. Results. Before and within the first 100 days after transplantation, patients' peripheral blood mononuclear cell (PBMC) presented an oligoclonal or polyclonal skewed T cell repertoire, low T cell receptor excision circles (TRECs) values and predominance of CD45RO+ T cell. In contrast, the presence of high numbers of CD45RA+ T cells in bone marrow(BM) circulation reconstituted SCID patients (>100 days post-transplantation) correlated with active T cell production by the thymus as revealed by high TREC values, and a polyclonal T cell repertoire demonstrated by a Gaussian distribution of Vβ-specific peaks. Conclusions. Within one year after BMT, a normal T cell repertoire develops in SCID patients as a result of thymic output. The T cell receptor diversity is highly and positively correlated in these patients with TREC levels.

  10. Immunizations in solid organ and hematopoeitic stem cell transplant patients: A comprehensive review

    L'Huillier, Arnaud G; Kumar, Deepali

    2015-01-01

    The Solid Organ Transplantation (SOT) and Haematopoietic Stem Cell Transplantation (HSCT) population is continuously increasing as a result of broader indications for transplant and improved survival. Infectious diseases, including vaccine-preventable diseases, are a significant threat for this population, primarily after but also prior to transplantation. As a consequence, clinicians must ensure that patients are optimally immunized before transplantation, to provide the best protection during the early post-transplantation period, when immunosuppression is the strongest and vaccine responses are poor. After 3–6 months, inactivated vaccines immunization can be resumed. By contrast, live-attenuated vaccines are lifelong contraindicated in SOT patients, but can be considered in HSCT patients at least 2 years after transplantation, if there is no immunosuppression or graft-versus-host-disease. However, because of the advantages of live-attenuated over inactivated vaccines - and also sometimes the absence of an inactivated alternative - an increasing number of prospective studies on live vaccine immunization after transplantation are performed and give new insights about safety and immunogenicity in this population.

    Full Text Available The aim of this study was to determine the incidence and causes of fever as a major problem contributing to transplantation related mortality among patients undergoing hematopoietic stem cell transplantation (HSCT and evaluation of antibiotic use, according to reliable guidelines.We retrospectively reviewed hospital records of 195 adult patients who underwent HSCT between 2009-2011 at hematology-oncology and bone marrow transplantation research center. Baseline information and also data related to fever and neutropenia, patient's outcomes, duration of hospitalization and antibiotic use pattern were documented.A total of 195 patients were analyzed and a total of 268 febrile episodes in 180 patients were recorded (mean 1.5 episodes per patient. About 222 episodes (82% were associated with neutropenia which one-fourth of them were without any documented infection sources. Microbiologic documents showed that the relative frequencies of gram positive and gram negative bacteria were 62.5% and 37.5%, respectively. The hospital stay duration was directly related to the numbers of fever episodes (P<0.0001.The rate of febrile episodes in autologous stem cell transplantation was significantly higher compared to allogeneic type (P<0.05.It is necessary to determine not only the local profile of microbiologic pattern, but also antibiotic sensitivities in febrile neutropenic patients following hematopoietic stem cell transplantation, and reassess response to antibiotic treatment to establish any necessity for modifications to treatment guidelines in order to prevent any fatal complications from infection.

    Full Text Available Introduction: Autologous haemopoietic stem cell transplantation (SCT is an important treatment modality for patients with acute myeloid leukemia with low and intermediate risk disease. It has served advantages over allogenic transplantation, because it does not need a matched donor, there is no graft versus host disease, there are less complications and a faster immune reconstitution than in the allo-setting. The disadvantage is the lack of the graft versus leukaemia effect.

    X-linked agammaglobulinemia (XLA) is a primary immunodeficiency characterized by marked reduction in all classes of serum immunoglobulins and the near absence of mature CD19(+) B-cells. Although malignancy has been observed in patients with XLA, we present the first reported case of acute myeloid leukemia (AML) in a patient with XLA. We also demonstrate the complete correction of the XLA phenotype following allogeneic hematopoietic cell transplantation for treatment of the patient's leukemia.

    We tested whether multi-parameter immune phenotyping before or after renal ­transplantation can predict the risk of rejection episodes. Blood samples collected before and weekly for 3 months after transplantation were analyzed by multi-parameter flow cytometry to define 52 T cell and 13 innate lymphocyte subsets in each sample, producing more than 11,000 data points that defined the immune status of the 28 patients included in this study. Principle component analysis suggested that the patients with histologically confirmed rejection episodes segregated from those without rejection. Protein death 1 (PD-1)-expressing subpopulations of regulatory and conventional T cells had the greatest influence on the principal component segregation. We constructed a statistical tool to predict rejection using a support vector machine algorithm. The algorithm correctly identified 7 out of 9 patients with rejection, and 14 out of 17 patients without rejection. The immune profile before transplantation was most accurate in determining the risk of rejection, while changes of immune parameters after transplantation were less accurate in discriminating rejection from non-rejection. The data indicate that pretransplant immune subset analysis has the potential to identify patients at risk of developing rejection episodes, and suggests that the proportion of PD1-expressing T cell subsets may be a key indicator of rejection risk.

    The aim of this study is to explore the effectiveness of autologous peripheral hematopoietic stem-cell transplantation in the treatment of refractory pemphigus.A 35-year-old male patient presented with a 4-year history of recurrent bullae on his trunk and extremities.The diagnosis of pemphigus was made on the basis of the clinical,histologic and immunofluorescence findings.The patient had shown resistance to conventional therapy with glucocorticoid and immunosuppressive agents.Two months before admission,he complained of hip joint pain.X-ray and CT scan revealed aseptic necrosis of the femoral head.Stem-cell mobilization was achieved by treatment with cyclophosphamide,granulocyte colony-stimulating factor (G-CSF)and rituximab.Peripheral blood stem cells were collected via leukapheresis and cryopreserved for later use.Immunoablation was accomplished by using cyclophosphamide(200 mg/kg;divided into 50 mg/kg on days-5,-4,-3,and-2),antithymocyte globulin(ATG;10 mg/kg;divided into 2.5 mg/kg on days-6,-5,-4,and-3),and rituximab (1200 mg/d;divided into 600 mg/d on days 0 and 7).Autologous peripheral hematopoietic stem cell transplantation was followed by reconstitution of the immune system which was monitored by flow cytometry.The glucocorticoid was withdrawn immediately after transplantation.The pemphigus titer turned negative 6 weeks after transplantation and remained negative.The patient was in complete drug-free remission with no evidence of residual clinical or serological activity of pemphigus during 1 year of followup.The patient's response suggests that autologous peripheral hematopoietic stem cell transplantation may be a potential "cure" for refractory pemphigus.However,further studies are needed to evaluate the risk-benefit ratio of this approach in patients with pemphigus showing resistance to conventional therapy.

    Background Many treatment options for lower limb ischemia are difficult to apply for the patients with poor arterial outflow or with poor general conditions.The effect of medical treatment alone is far from ideal.especially in patients with diabetic foot.A high level amputation is inevitable in these patients.This study aimed to explore the effect of transplantation of autologous bone marrow mononuclear cells on the treatment of lower limb ischemia and to compare the effect of intra-artedal transplantation with that of intra-muscular transplantation.Methods In this clinical trial,32 patients with lower limb ischemia were divided into two groups.Group 1 (16 patients with 18 affected limbs) received transplantation of autologous bone marrow mononuclear cells by intra-muscular injection into the affected limbs;and group 2(16 patients with 17 affected limbs)received transplantation of autologous bone marrow mononucJear cells by intra-arterial injection into the affected limbs.Rest pain,coldness,ankle/brachial index (ABI),claudication,transcutaneous oxygen pressure(tcPO2)and angiography(15 limbs of 14 patients)were evaluated before and after the mononuclear cell transplantation to determine the effect of the treatment.Results Two patients died from heart failure.The improvement of rest pain was seen in 76.5%(13/17)of group 1 and 93.3%(14/15)of group 2.The improvement of coldness was 100%in both groups.The increase of ABI was 44.4%(8/18)in group 1 and 41.2%(7,17)in group 2.The value of tcPO2 increased to 20 mmHg or more in 20 limbs.Nine of 15 limbs which underwent angiography showed rich collaterals.Limb salvage rate was 83.3%(15,18)in group 1 and 94.1%(16/17)in group 2.There was no statistically significant difference in the effectiveness of the treatment between the two groups.Conclusions Transplantation of autologous bone marrow mononucJear cells is a simple,safe and effective method for the treatment of lower limb ischemia,and the two approaches for the implantation

    Although a large number of amyotrophic lateral sclerosis (ALS) patients have undergone transplantation procedures with olfactory ensheathing cells (OECs) in the Bejing Hospital, to our knowledge, no post-mortem neuropathologic analyses have been performed. We examined the post-mortem brain of two Italian patients affected by ALS who underwent cellular transplantation in Beijing with their consent. Our aim was to assess the events following the graft procedure to possibly support the rationale of the treatment strategy. The neuropathologic findings were analyzed on the basis of the limited awareness of the experimental conditions and discussed in relation to the safety, efficacy and long-term outcome of the transplanted cells. Islands of quiescent, undifferentiated cells within the delivery track persisting for up to 12 months-24 months were found. Prominent glial and inflammatory reaction around the delivery track strongly supports the encasement of the graft. Evidence of axonal regeneration, neuronal differentiation and myelination was not seen. The surgical procedure of implantation was not compatible with a neurotrophic effect. The OEC transplantation did not modify the neuropathology of ALS in the two patients. In conclusion, the present neuropathologic analysis does not support a beneficial effect of fetal OEC implantation into the frontal lobes of ALS patients.

    Full Text Available ABSTRACT Introduction: Patients submitted to hematopoietic stem cell transplantation have an increased risk of Clostridium difficile infection and multiple risk factors have been identi- fied. Published reports have indicated an incidence from 9% to 30% of transplant patients however to date there is no information about infection in these patients in Chile. Methods: A retrospective analysis was performed of patients who developed C. difficile infection after hematopoietic stem cell transplantations from 2000 to 2013. Statistical analysis used the Statistical Package for the Social Sciences software. Results: Two hundred and fifty patients were studied (mean age: 39 years; range: 17-69, with 147 (59% receiving allogeneic transplants and 103 (41% receiving autologous trans- plants. One hundred and ninety-two (77% patients had diarrhea, with 25 (10% cases of C. difficile infection being confirmed. Twenty infected patients had undergone allogeneic trans- plants, of which ten had acute lymphoblastic leukemia, three had acute myeloid leukemia and seven had other diseases (myelodysplastic syndrome, chronic myeloid leukemia, severe aplastic anemia. In the autologous transplant group, five patients had C. difficile infection; two had multiple myeloma, one had amyloidosis, one had acute myeloid leukemia and one had germinal carcinoma. The overall incidence of C. difficile infection was 4% within the first week, 6.4% in the first month and 10% in one year, with no difference in overall survival between infected and non-infected groups (72.0% vs. 67.6%, respectively; p-value = 0.56. Patients infected after allogeneic transplants had a slower time to neutrophil engraftment compared to non-infected patients (17.5 vs. 14.9 days, respectively; p-value = 0.008. In the autologous transplant group there was no significant difference in the neutrophil engraftment time between infected and non-infected patients (12.5 days vs. 11.8 days, respectively; p

    Allogeneic hematopoietic stem cell transplantation (HSCT) represents the only curative treatment for patients with myelodysplastic syndrome (MDS), but involves non-negligible morbidity and mortality. Registry studies have shown that advanced disease stage at transplantation is associated with inferior overall survival. To define the optimal timing of allogeneic HSCT, we carried out a decision analysis by studying 660 patients who received best supportive care and 449 subjects who underwent transplantation. Risk assessment was based on both the International Prognostic Scoring System (IPSS) and the World Health Organization classification-based Prognostic Scoring System (WPSS). We used a continuous-time multistate Markov model to describe the natural history of disease and evaluate the effect of allogeneic HSCT on survival. This model estimated life expectancy from diagnosis according to treatment policy at different risk stages. Relative to supportive care, estimated life expectancy increased when transplantation was delayed from the initial stages until progression to intermediate-1 IPSS-risk or to intermediate WPSS-risk stage, and then decreased for higher risks. Modeling decision analysis on WPSS versus IPSS allowed better estimation of the optimal timing of transplantation. These observations indicate that allogeneic HSCT offers optimal survival benefits when the procedure is performed before MDS patients progress to advanced disease stages.

    To explore the correlation between hypoimmunity and the occurrence of pure red cell aplasia (PRCA) in senile patients undergoing combined pancrease-kindey transplantation. Methods: PRCA occurred in 2 patients out of 5 who were performed combined pancrease-kindey transplantation.The general scheme of treatment mainly included selective administration of immunosuppressants and antivirus drugs, infusion of red blood cells on the basis of surveillance of parvorirus B19 and the ratio of T4 and T8 as well as the changes of the myelogram.Results: The myelogram of the patients returned to normal in 2 and 3 weeks after operation, respectively, and subsequent follow-up revealed no recurrence. Conclusion: This series illustrate the point that advanced age, hypo immunity, parvorirus B19 and immunosuppressants are vulnerable to PRCA. Combined treatment is an effectiveremedy for these patients.

    Acquired pure red-cell aplasia is a rare disorder that can be either idiopathic or associated with certain autoimmune diseases, pregnancy, lymphoproliferative disorders, nutritional deficiencies, or medicines. We present a deceased-donor renal transplant patient who developed pure red-cell aplasia associated with mycophenolate mofetil or tacrolimus and was treated with cyclosporine. A 20-year-old woman was transplanted from a deceased donor 1 month earlier and presented to us with symptoms of fatigue, prostration, and palpitation. The results of a laboratory examination revealed anemia. A diagnostic work-up resulted in a diagnosis of pure red-cell aplasia. Mycophenolate mofetil was discontinued. Tacrolimus also was replaced with cyclosporine 2 months after mycophenolate mofetil was halted because of a lack of improvement in anemia. Three months later, her anemia improved with cyclosporine. Starting cyclosporine instead of tacrolimus or mycophenolate mofetil showed good improvement in our patient within 6 months of therapy.

    Elderly patients (>60 years) with acute myeloid leukemia have a poor prognosis with a chemotherapy-alone approach. Allogeneic hematopoietic-cell transplantation (HCT) can improve overall survival (OS). However, myeloablative regimens can have unacceptably high transplant-related mortality (TRM) in an unselected group of older patients. Reduced-intensity conditioning (RIC) or nonmyeloablative (NMA) conditioning regimens preserve the graft-versus-leukemia effects but reduce TRM. NMA regimens result in minimal cytopenia and may not require stem cell support for restoring hematopoiesis. RIC regimens, intermediate in intensity between NMA and myeloablative regimens, can cause prolonged myelosuppresion and usually require stem cell support. A few retrospective and prospective studies suggest a possibility of lower risk of relapse with myeloablative HCT in fit older patients with lower HCT comorbidity index; however, RIC and NMA HCTs have an important role in less-fit patients and those with significant comorbidities because of lower TRM. Whether early tapering of immunosuppression, monitoring of minimal residual disease, and post-transplant maintenance therapy can improve the outcomes of RIC and NMA HCT in elderly patients will require prospective trials.

    Background Multiple sclerosis (MS) is a continuously disabling disease and it is unresponsive to high dose steroid and immunomodulation with disease progression. The autologous haematopoietic stem cell transplantation (ASCT) has been introduced in the treatment of refractory forms of multiple sclerosis. In this study, the clinical outcomes followed by ASCT were evaluated for patients with progressive MS.Methods Twenty-two patients with secondary progressive MS were treated with ASCT. Peripheral blood stem cells were obtained by leukapheresis after mobilization with granulocyte colony stimulating factor. Etoposide,melphalan, carmustin and cytosine arabinoside were administered as conditioning regimen. Outcomes were evaluated by the expanded disability status scale and progression free survival. No maintenance treatment was administered during a median follow-up of 39 months (range, 6 to 59 months).Results No death occurred following the treatment. The overall confirmed progression free survival rate was77% up to 59 months after transplantation which was significantly higher compared with pre-transplantation (P=0.000). Thirteen patients (59%) had remarkable improvement in neurological manifestations, four (18%)stabilized their disability status and five (23%) showed clinical recurrence of active symptoms.Conclusions ASCT as a therapy is safe and available. It can improve or stabilize neurological manifestations in most patients with progressive MS following failure of conventional therapy.

    Full Text Available Despite advances in the field, a clear treatment algorithm for most peripheral T-cell lymphoma (PTCL subtypes remains to be defined. Generating reliable randomized data for this type of pathology remains a challenge because of the relative rarity of the disease and the heterogeneity of subtypes. Newer agents, such as the class-I selective histone deacetylase inhibitor romidepsin, have demonstrated efficacy and manageable toxicity in the relapsed and refractory setting. Whether novel agents should be used in conjunction with more conventional cytotoxic therapies or in sequence with a transplant strategy is unknown at this time. Here we report the successful use of romidepsin monotherapy as a bridge to allogeneic stem cell transplantation in a patient who had previously relapsed after several lines of conventional cytotoxic therapy for PTCL. Romidepsin provided the patient with sufficient disease control to proceed to transplantation while remaining in complete remission.

    Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired hemolytic anemia caused by lack of CD55 and CD59 on blood cell membrane leading to increased sensitivity of blood cells to complement. Hematopoietic stem cell transplantation (HSCT) is the only curative therapy for PNH, however, lack of HLA-matched donors and post-transplant complications are major concerns. Induced pluripotent stem cells (iPSCs) derived from patients are an attractive source for generating autologous HSCs to avoid adverse effects resulting from allogeneic HSCT. The disease involves only HSCs and their progeny; therefore, other tissues are not affected by the mutation and may be used to produce disease-free autologous HSCs. This study aimed to derive PNH patient-specific iPSCs from human dermal fibroblasts (HDFs), characterize and differentiate to hematopoietic cells using a feeder-free protocol. Analysis of CD55 and CD59 expression was performed before and after reprogramming, and hematopoietic differentiation. Patients' dermal fibroblasts expressed CD55 and CD59 at normal levels and the normal expression remained after reprogramming. The iPSCs derived from PNH patients had typical pluripotent properties and differentiation capacities with normal karyotype. After hematopoietic differentiation, the differentiated cells expressed early hematopoietic markers (CD34 and CD43) with normal CD59 expression. The iPSCs derived from HDFs of PNH patients have normal levels of CD55 and CD59 expression and hold promise as a potential source of HSCs for autologous transplantation to cure PNH patients.

    Full Text Available BACKGROUND: Neural stem cells are currently being investigated as potential therapies for neurodegenerative diseases, stroke, and trauma. However, concerns have been raised over the safety of this experimental therapeutic approach, including, for example, whether there is the potential for tumors to develop from transplanted stem cells. METHODS AND FINDINGS: A boy with ataxia telangiectasia (AT was treated with intracerebellar and intrathecal injection of human fetal neural stem cells. Four years after the first treatment he was diagnosed with a multifocal brain tumor. The biopsied tumor was diagnosed as a glioneuronal neoplasm. We compared the tumor cells and the patient's peripheral blood cells by fluorescent in situ hybridization using X and Y chromosome probes, by PCR for the amelogenin gene X- and Y-specific alleles, by MassArray for the ATM patient specific mutation and for several SNPs, by PCR for polymorphic microsatellites, and by human leukocyte antigen (HLA typing. Molecular and cytogenetic studies showed that the tumor was of nonhost origin suggesting it was derived from the transplanted neural stem cells. Microsatellite and HLA analysis demonstrated that the tumor is derived from at least two donors. CONCLUSIONS: This is the first report of a human brain tumor complicating neural stem cell therapy. The findings here suggest that neuronal stem/progenitor cells may be involved in gliomagenesis and provide the first example of a donor-derived brain tumor. Further work is urgently needed to assess the safety of these therapies.

    Full Text Available BACKGROUND: Factors affecting the efficacy of platelet and red blood cell (RBC transfusion in patients undergoing hematopoietic stem cell transplantation (HSCT have not been studied extensively. We aimed to evaluate platelet and RBC transfusion efficacy by measuring the platelet corrected count increment and the hemoglobin increment, respectively, 24 h after transfusion in 105 patients who received HSCT. METHODOLOGY/PRINCIPAL FINDINGS: Using retrospective analysis, we studied whether factors, including gender, time of transplantation, the compatibility of ABO group between HSC donors and recipients, and autologous or allogenic transplantation, influence the efficacy of blood component transfusion. We found that the infection rate of HSCT patients positively correlated with the transfusion amount, and the length of stay in the laminar flow room was associated with transfusion. We found that platelet transfusion performed during HSCT showed significantly better efficacy than that performed before HSCT. The effect of platelet transfusion in auto-transplantation was significantly better than that in allo-transplantation. The efficacy of RBC transfusion during HSCT was significantly lower than that performed before HSCT. The efficacy of RBC transfusion in auto-transplantation was significantly higher than that in allo-transplantation. Allo-transplantation patients who received HSCs from compatible ABO groups showed significantly higher efficacy during both platelet and RBC transfusion. CONCLUSIONS: We conclude that the efficacy of platelet and RBC transfusions does not correlate with the gender of patients, while it significantly correlates with the time of transplantation, type of transplantation, and ABO compatibility between HSC donors and recipients. During HSCT, the infection rate of patients positively correlates with the transfusion amount of RBCs and platelets. The total volume of RBC units transfused positively correlates with the length of

    Background The effect of pre-transplant conditioning upon the long-term outcomes of patients receiving hematopoietic stem cell transplantation (HSCT) for severe combined immunodeficiency (SCID) has not been completely determined. Objective To assess the outcomes of 23 mostly conditioned SCID patients and compare their outcomes to 25 nonconditioned SCID transplanted patients previously reported. Methods In the present study, we reviewed the medical records of these 23 consecutive mostly conditioned SCID patients transplanted between 1998 and 2007. Results Eighteen patients (median age at transplant 10 [range 0.8–108] mo) received haploidentical mismatched related donor, matched unrelated donor, or mismatched unrelated donor transplants, 17 of whom received pretransplant conditioning and one was not conditioned, 13 (72%) engrafted and survive a median of 3.8 [1.8–9.8] yr, 5 of 13 (38%) require IVIG, and 6 of 6 age-eligible children attend school. Of five recipients (median age at transplant 7 [range 2–23] mo) of matched related donor transplants, all 5 engrafted and survive a median of 7.5 [range 1.5–9.5] yr, 1 requires IVIG, and 3 of 3 age-eligible children attend school. Gene mutations were known in 16 cases: IL2γR in 7 patients, IL7αR in 4 patients, RAG1 in 2 patients, ADA in 2 patients, and AK2 in 1 patient. Early outcomes and quality of life of the previous non-conditioned vs. the present conditioned cohorts were not statistically different but longer-term follow-up is necessary for confirmation. Conclusions HSCT in SCID patients results in engraftment, long-term survival, and a good quality of life for the majority of patients with or without pre-transplant conditioning. PMID:19895994

    Full Text Available Allogeneic hematopoietic cell transplantation has become a viable option for younger patients with poor-risk chronic lymphocytic leukemia. The results obtained with either conventional or reduced-intensity conditioning regimens have been recently evaluated and compared with alternative nontransplant strategies. This manuscript deals with practical aspects of the procedure, including patient and donor selection, conditioning regimen, GVHD prophylaxis, disease monitoring, infectious and noninfectious complications, and timing of the procedure. Finally, we speculate on how we could improve the results obtained with the procedure and new advances currently in clinical trials.

    Full Text Available A compromised immune system places individuals at a significantly higher risk for many infectious processes. Immunosuppression also increases the risk of malignancy due to the body's decreased ability to perform its normal immunosurveilance and response. It is therefore imperative to have regular thorough evaluations of these patients, as slight abnormalities may be the early signs of infection or neoplasm. We present the first reported case of a tongue lesion in a stem cell transplant patient, highly concerning for malignancy, which was found to be a mucocutaneous presentation of disseminated Cryptococcus.

    Patients with hematologic malignancies undergoing allogeneic stem cell transplantation (HSCT) commonly have an elevated serum ferritin prior to HSCT, which has been associated with increased mortality after transplantation. This has led to the suggestion that iron overload is common and deleterious in this patient population. However, the relationship between serum ferritin and parenchymal iron overload in such patients is unknown. We report a prospective study of 48 patients with acute leukemia (AL) or myelodysplastic syndromes (MDS) undergoing myeloablative HSCT, using magnetic resonance imaging (MRI) to estimate liver iron content (LIC) and cardiac iron. The median (and range) pre-HSCT value of serum ferritin was 1549 ng/mL (20-6989); serum hepcidin, 59 ng/mL (10-468); labile plasma iron, 0 LPI units (0.0-0.9). Eighty-five percent of patients had hepatic iron overload (HIO), and 42% had significant HIO (LIC ≥5.0 mg/gdw). Only 1 patient had cardiac iron overload. There was a strong correlation between pre-HSCT serum ferritin and estimated LIC (r = .75), which was mostly dependent on prior transfusion history. Serum hepcidin was appropriately elevated in patients with HIO. Labile plasma iron elevation was rare. A regression calibration analysis supported the hypothesis that elevated pre-HSCT LIC is significantly associated with inferior post-HSCT survival. These results contribute to our understanding of the prevalence, mechanism, and consequences of iron overload in HSCT.

    Background Up to 70% of patients receiving hematopoietic stem cell transplant develop oral mucositis as a side effect of high-dose melphalan conditioning chemotherapy. Oral cryotherapy has been documented to be potentially effective in reducing oral mucositis. The aim of this study was to examine the effectiveness of the cryotherapy protocol implemented within the hematopoietic stem cell transplant program. Methods A retrospective chart review was conducted of adult multiple myeloma patients who received high-dose melphalan conditioning therapy for autologous hematopoietic stem cell transplant. Primary endpoints were incidence and severity of oral mucositis. Secondary endpoints included duration of oral mucositis, duration of hospital stay, parenteral narcotics use and total parenteral nutrition use. Results One hundred and forty patients were included in the study, 70 patients in both no cryotherapy and cryotherapy groups. Both oral mucositis incidence and severity were found to be significantly lower in the cryotherapy group. Fifty (71.4%) experienced mucositis post cryotherapy compared to 67 (95.7%) in the no cryotherapy group (p < 0.001). The median oral mucositis severity, assessed using the WHO oral toxicity scale from grade 0-4, experienced in the no group was 2.5 vs. 2 in the cryotherapy group (p = 0.03). Oral mucositis duration and use of parenteral narcotics were also significantly reduced. Duration of hospital stay and use of parenteral nutrition were similar between the two groups. Conclusion The cryotherapy protocol resulted in a significantly lower incidence and severity of oral mucositis. These results provide evidence for the continued use of oral cryotherapy, an inexpensive and generally well-tolerated practice.

    Background Chimerism analysis is an important tool for the surveillance of post-transplant engraftment.It offers the possibility of identifying impending graft rejection and recurrence of underlying malignant or non-malignant disease.Here we investigated the quantitative chimerism kinetics of 21 relapsed leukemia patients after allogeneic hematopoietic stem cell transplantation (HSCT).Methods A panel of 29 selected sequence polymorphism (SP) markers was screened by real-time polymerase chain reaction (RT-PCR) to obtain the informative marker for every leukemia patient.Quantitative chimerism analysis of bone marrow (BM) samples of 21 relapsed patients and 20 patients in stable remission was performed longitudinally.The chimerisms of BM and peripheral blood (PB) samples of 14 patients at relapse were compared.Results Twenty-one patients experienced leukemia relapse at a median of 135 days (range,30-720 days) after transplantation.High recipient chimerism in BM was found in all patients at relapse,and increased recipient chimerism in BM samples was observed in 90% (19/21) of patients before relapse.With 0.5% recipient DNA as the cut-off,median time between the detection of increased recipient chimerism and relapse was 45 days (range,0-120 days),with 76% of patients showing increased recipient chimerism at least 1 month prior to relapse.Median percentage of recipient DNA in 20 stable remission patients was 0.28%,0.04%,0.05%,0.05%,0.08%,and 0.05% at 1,2,3,6,9,and 12 months,respectively,after transplantation.This was concordant with other specific fusion transcripts and fluorescent in situ hybridization examination.The recipient chimerisms in BM were significantly higher than those in PB at relapse (P=0.001).Conclusions This SP-based RT-PCR essay is a reliable method for chimerism analysis.Chimerism kinetics in BM can be used as a marker of impending leukemia relapse,especially when no other specific marker is available.Based on our findings

    Full Text Available Abstract Background Beta thalassemia major is a severe inherited form of hemolytic anemia that results from ineffective erythropoiesis. Allogenic hematopoietic stem cell transplantation (HSCT remains the only potentially curative therapy. Unfortunately, the subgroup of adult thalassemia patients with hepatomegaly, portal fibrosis and a history of irregular iron chelation have an elevated risk for transplantation-related mortality that is currently estimated to be about 29 percent. Discussion Thalassemia patients may be faced with a difficult choice: they can either continue conventional transfusion and iron chelation therapy or accept the high mortality risk of HSCT in the hope of obtaining complete recovery. Throughout the decision making process, every effort should be made to sustain and enhance autonomous choice. The concept of conscious consent becomes particularly important. The patient must be made fully aware of the favourable and adverse outcomes of HSCT. Although it is the physician's duty to illustrate the possibility of completely restoring health, considerable emphasis should be put on the adverse effects of the procedure. The physician also needs to decide whether the patient is eligible for HSCT according to the "rule of descending order". The patient must be given full details on self-care and fundamental lifestyle changes and be fully aware that he/she will be partly responsible for the outcome. Summary Only if all the aforesaid conditions are satisfied can it be considered reasonable to propose unrelated HSCT as a potential cure for high risk thalassemia patients.

    Although delirium is a common medical comorbidity with altered cognition as its defining feature, few publications have addressed the neuropsychological prodrome, profile, and recovery of patients tested during delirium. We characterize neuropsychological performance in 54 hemapoietic stem cell/bone marrow transplantation (BMT) patients shortly before, during, and after delirium and in BMT patients without delirium and 10 healthy adults. Patients were assessed prospectively before and after transplantation using a brief battery. BMT patients with delirium performed more poorly than comparisons and those without delirium on cross-sectional and trend analyses. Deficits were in expected areas of attention and memory, but also in psychomotor speed and learning. The patients with delirium did not return to normative “average” on any test during observation. Most tests showed a mild decline in the visit before delirium, a sharp decline with delirium onset, and variable performance in the following days. This study adds to the few investigations of neuropsychological performance surrounding delirium and provides targets for monitoring and early detection; Trails A and B, RBANS Coding, and List Recall may be useful for delirium assessment.

    Background and Objectives Use of pluripotent stem cells is an ideal solution for liver insufficiencies. This work aims is to evaluate the safety and feasibility of autologous stem cells transplantation (SCT) in Egyptian patients of liver cirrhosis on top of hepatitis C virus (HCV). Subjects and Results 20 patients with HCV induced liver cirrhosis were divided into 2 groups. Group I: included 10 patients with liver cirrhosis Child score ≥9, for whom autologous stem cell transplantation was done using granulocyte colony stimulating factor (G-CSF) for stem cells mobilization. Separation and collection of the peripheral blood stem cells was done by leukapheresis. G-CSF mobilized peripheral blood mononuclear cells (G-CSF PB-MNCs) were counted by flow cytometry. Stem cell injection into the hepatic artery was done. Group II: included 10 patients with HCV induced liver cirrhosis as a control group. Follow up and comparison between both groups were done over a follow up period of 6 months. The procedure was well tolerated. Mobilization was successful and the total number of G-CSF PB-MNCs in the harvests ranged from 25×106 to 191×106. There was improvement in the quality of life, serum albumin, total bilirubin, liver enzymes and the Child-Pugh score of group I over the first two-three months after the procedure. Conclusion SCT in HCV induced liver cirrhosis is a safe procedure. It can improve the quality of life and hepatic functions transiently with no effect on the life expectancy or the fate of the liver cirrhosis. PMID:26634069

    Full Text Available Hematopoietic stem cells are usually transfused through a central venous catheter (CVC, which also facilitates administration of medications and intravenous fluids. We had observed high rate of catheter-related blood-stream infection (CR-BSI at our Bone Marrow Transplantation (BMT unit despite prescribing fluoroquinolones for anti-bacterial prophylaxis. Accordingly, we implemented prophylactic use of a relatively inexpensive broad spectrum antibiotic, namely doxycycline to address this problem. We wanted to investigate whether doxycycline prophylaxis reduces CR-BSI rate. Data was collected retrospectively on 54 consecutive patients, 26 of whom received doxycycline (doxycycline group, and we compared their outcomes to a previous cohort of 28 patients who did not receive doxycycline (comparison group. The groups were comparable in regards to age, gender, hematopoietic cell transplant type, and primary diagnosis. No CVC infection (0% was observed in the doxycycline group, while 5 infection episodes (18.5% occurred in 4 patients in the comparison group (p<0.001. Episodes of CR-BSI were due to: Escherichia-coli (EC=1, coagulase-negative Staphylococcus-spp (CNSS=2, both EC & CNSS=1. Our results demonstrate that CR-BSI was reduced significantly after introducing doxycycline. This finding suggests a beneficial role for systemic use of doxycycline prophylaxis to prevent CR-BSI in adult BMT patients. Nevertheless, a randomized controlled study is warranted to confirm these findings.

    Combination antiretroviral therapy (cART) effectively suppresses viral load in HIV-infected individuals, but it is not a cure. Bone marrow transplants using HIV-resistant stem cells have renewed hope that cure is achievable but key questions remain e.g., what percentage of stem cells must be HIV-resistant to achieve cure?. As few patients have undergone transplants, we built a mechanistic model of HIV/AIDS to approach this problem. The model includes major players of infection, reproduces the complete course of the disease, and simulates crucial components of clinical treatments, such as cART, irradiation, host recovery, gene augmentation, and donor chimerism. Using clinical data from 172 cART-naïve HIV-infected individuals, we created virtual populations to predict performance of CCR5-deficient stem-cell therapies and explore interpatient variability. We validated our model against a published clinical study of CCR5-modified T-cell therapy. Our model predicted that donor chimerism must exceed 75% to achieve 90% probability of cure across patient populations.

    Objective: To evaluate whether stem cell transplantation improves global left ventricular ejection fraction (LVEF) in patients with acute myocardial infarction (AMI), and to determine the appropriate stem cell therapy dose as well as the effective period after stem cell transplantation for therapy. Methods: A systematic literature search included Pubmed, MEDLINE, China National Knowledge Infrastructure (CNKI), Chi-nese Biomedical Literature Database (CBM), and Cochrane Evidence-Based Medicine databases. The retrieval time limit ranged from January 1990 to June 2016. We also obtained full texts through manual retrieval, interlibrary loan and document delivery service, or by contacting the authors directly. According to our inclusion and exclusion criteria, data were extracted independently by two evaluators. In case of disagreement, a joint discussion occurred and a third researcher was utilized. Data were analyzed quantitatively using Revman 5.2. Summary results are presented as the weighted mean difference (WMD) with 95%confidence intervals (CIs). We collected individual trial data and conducted a meta-analysis to compare changes in global left ventricular ejection fraction (△LVEF) after stem cell therapy. In this study, four subgroups were based on stem cell dose (≤1 × 107 cells,≤1 × 108 cells,≤1 × 109 cells, and≤1 × 1010 cells) and three subgroups were based on follow-up time (<6 months, 6-12 months, and≥12 months). Results: Thirty-four studies, which included 40 randomized controlled trials, were included in this meta-analysis, and 1927 pa-tients were evaluated. Changes in global LVEF were significantly higher in the stem cell transplantation group than in the control group (95% CI: 2.35-4.26%, P < 0.01). We found no significant differences in △LVEF between the bone marrow stem cells (BMCs) group and control group when the dose of BMCs was≤1 × 107 [△LVEF 95%CI:0.12-3.96%, P=0.04]. The△LVEF in the BMCs groups was significantly higher

    Objective:To discuss whether nutritional risk screening 2002 (NRS2002) is appropriate for nutritional risk screening for leukemia patients before and after hematopoietic stem cell transplantation (HSCT),and whether there are risk differences in other conditions,such as age,gender and matching degree; to find the methods and indicators of nutritional risk screening for these patients before and after HSCT,in order to give timely intervention to guarantee the successful completion of the entire transplantation process.Methods:Nutritional risk of 99 leukemia patients was screened with NRS2002 before and after HSCT.The x2 test was applied to compare the risk differences between groups such as age,gender and matching degree,while the differences of other enumeration data,such as recent (1-3 months) weight loss,reduced food intake within one week and BMI,were compared by continuity correction.Results:Of the 99 leukemia patients,22 cases (22.2%) had nutritional risk before HSCT,while all patients had nutritional risk after HSCT; there is no significant difference in nutritional risk between male and female,and patients of less than 30 years old,not-full matched,recent (1-3 months) weight loss,reduced food intake within a week or BMI <18.5 were more likely to have nutritional risk; and 77 cases (77.8%) had weight loss,among which 49 patients (63.6%) had more than 5% weight loss within one month.Conclusions:This study showed that leukemia patients should receive the nutritional risk screening conventionally before and after HSCT,and NRS2002 was only appropriate for nutritional risk screening before HSCT.More attention should be paid to the patients less than 30 years old or not-full matched.Weight change was one of the important nutritional indicators for patients after HSCT.

    Objectives. This study examines the short- and long-term QOL benefits of a music therapy intervention for patients recovering from hematopoietic stem cell transplantation (HSCT). Methods. Ninety allogeneic HSCT patients, after transplant, were randomized to receive ISO-principle (i.e., mood matching) based music therapy (MT; n = 29), unstructured music (UM; n = 30), or usual care (UC; n = 31) for four weeks. The ISO principle posits that patients may shift their mood from one state to another by listening to music that is "equal to" the individual's initial mood state and subsequently listening to music selections that gradually shift in tempo and mood to match the patient's desired disposition. Participants in MT and UM groups developed two audio CDs to help them feel more relaxed and energized and were instructed to use the CDs to improve their mood as needed. Short-term effects on mood and long-term effects on QOL were examined. Results. MT and UM participants reported improved mood immediately after listening to CDs; the within-group effect was greater for UM participants compared to MT participants. Participant group was not associated with long-term QOL outcomes. Conclusions. Music listening improves mood acutely but was not associated with long-term benefits in this study.

    Full Text Available &lt;b&gt;Purpose:&lt;/b&gt; Lymphocyte subset recovery is an important factor that determines the success of hematopoietic stem cell transplantation (HSCT. Temporal differences in the recovery of lymphocyte subsets and the factors influencing this recovery are important variables that affect a patient's posttransplant immune reconstitution, and therefore require investigation. &lt;b&gt;Methods:&lt;/b&gt; The time taken to achieve lymphocyte subset recovery and the factors influencing this recovery were investigated in 59 children who had undergone HSCT at the Department of Pediatrics, The Catholic University of Korea Seoul St. Mary's Hospital, and who had an uneventful follow-up period of at least 1 year. Analyses were carried out at 3 and 12 months post-transplant. An additional study was performed 1 month post-transplant to evaluate natural killer (NK cell recovery. The impact of preand post-transplant variables, including diagnosis of Epstein-Barr virus (EBV DNAemia posttransplant,on lymphocyte recovery was evaluated. &lt;b&gt;Results:&lt;/b&gt; The lymphocyte subsets recovered in the following order: NK cells, cytotoxic T cells, B cells,and helper T cells. At 1 month post-transplant, acute graft-versus-host disease was found to contribute significantly to the delay of CD16+/56+ cell recovery. Younger patients showed delayed recovery of both CD3+/CD8+ and CD19+ cells. EBV DNAemia had a deleterious impact on the recovery of both CD3+ and CD3+/CD4+ lymphocytes at 1 year post-transplant. &lt;b&gt;Conclusion:&lt;/b&gt; In our pediatric allogeneic HSCT cohort, helper T cells were the last subset to recover. Younger age and EBV DNAemia had a negative impact on the post-transplant recovery of T cells and B cells.

    We report the results of 84 patients with ALL after related (n = 46) or unrelated (n = 38) allogeneic SCT. Mean recipient age was 23 years (range: 1-60) and median follow-up was 18 months (range: 1-133). Forty-three patients were transplanted in CR1; 25 in CR2 or CR3; four were primary refractory; four in PR; eight in relapse. The conditioning regimen consisted of TBI/VP16/CY (n = 76), TBI/VP16 (n = 2), TBI/CY (n = 2), Bu/VP16/CY (n = 4). The OS at 3 years was 45% (44% unrelated, 46% related). Univariate analysis showed a significantly better OS for patients <18 years (P=0.03), mismatched sex-combination (P = 0.03), both with a stronger effect on increasing OS after unrelated SCT. Factors decreasing TRM were patient age <18 years (P = 0.004), patient CMV-seronegativity (P = 0.014), female recipient (P = 0.04). There was no significant difference in TRM and the relapse rate was similar in both donor type groups. Multivariate analysis showed that factors for increased OS which remained significant were mismatched sex-combination (RR: 0.70,95% CI: 0.51-0.93, P = 0.015), patient age < 18 years (RR: 0.66, 95% CI: 0.47-0.93, P = 0.016). A decreased TRM was found for female patients (RR: 0.56, 95% CI: 0.33-0.98, P=0.042), negative CMV status of the patient (RR: 0.57, 95% CI: 0.36-0.90, P = 0.015). Unrelated stem cell transplantation for high-risk ALL patients with no HLA-compatible family donor is justifiable.

    Background Some leukemia patients before hematopoietic stem cell transplantation (HSCT) have nutritional risk or undernutrition,which was one of the main reasons that caused series of complications during transplantation.The aim of this study was to find out some appropriate methods to learn about the nutritional status of leukemia patients before HSCT.Methods Nutritional status of patients with leukemia was assessed with three common methods of nutritional assessment (nutritional risk screening 2002 (NRS2002),mini nutritional assessment (MNA) and subjective global assessment (SGA)) before HSCT.The assessment results of NRS2002 and MNA were compared by paired x2 test.The consistency was analyzed by Kappa test.Results In this study,13 of 50 patients (26.0%) with leukemia had nutritional risk before HSCT assessed by NRS2002,including 7 patients (14.0%) with undernutrition.Of 50 patients assessed by SGA,only 1 case (2.0%) was mild or moderate undernutrition,and the remaining 49 patients (98.0%) were well-nutrition.Assessed by MNA,1 case (2.0%)was undernutrition,11 cases (22.0%) were potential undernutrition,and 38 cases (76.0%) were well-nutrition.Paired x2 test results showed that the difference between NRS2002 and MNA was statistically significant (x2=13.64,P <0.05);Kappa test results showed that they were consistent between NRS2002 and MNA (Kappa=0.62,P<0.05).Conclusions It is important to know the nutritional status of patients with leukemia before HSCT,and NRS2002 should be the first choice of nutritional assessment for patients with leukemia.If NRS2002 and MNA used at the same time,the accuracy and comprehensiveness of the assessment can be improved.

    The first case of disseminated aspergillosis caused by Aspergillus ustus in an allogeneic peripheral stem cell transplant patient is described. The patient, a 46-year-old female with a history of myelodysplastic syndrome, underwent high-dose chemotherapy and total body irradiation prior to transplantation. She was released from the hospital 49 days posttransplant (p.t.) in a stable condition with an absolute neutrophil count (ANC) of 2,700 cells per microl. Multiple antimicrobial agents, including itraconazole (ITR), were prescribed during hospitalization and at the time of discharge. Three days after discharge, the patient was readmitted with hemorrhagic cystitis, persistent thrombocytopenia, and bilateral pulmonary consolidation, although no fever was present. The ANC at the time of readmission was 3,500. Upon detection of a pulmonary nodule (day 67 p.t.), a bronchoalveolar lavage was performed; the lavage fluid was positive for both cytomegalovirus and parainfluenza virus and negative for fungus. The patient was placed on ganciclovir. A biopsy specimen from a leg lesion also noted on day 67 p.t. revealed septate hyphae consistent with Aspergillus species, and a culture subsequently yielded Aspergillus ustus. Confirmation detection of A. ustus was made by demonstration of characteristic reproductive structures with the presence of Hülle cells. On day 67 p.t., ITR was discontinued and liposomal amphotericin B (AMB) was initiated. The patient's condition worsened, and she died 79 days p.t. At the time of autopsy, septate hyphae were present in heart, thyroid, and lung tissues, with lung tissue culture positive for A. ustus. In vitro susceptibility testing indicated probable resistance to AMB but not to ITR. This case supports the need for the development of rapid methods to determine antifungal susceptibility.

  1. Successful orthotopic liver transplantation in an adult patient with sickle cell disease and review of the literature

    Full Text Available Sickle cell disease can lead to hepatic complications ranging from acute hepatic crises to chronic liver disease including intrahepatic cholestasis, and iron overload. Although uncommon, intrahepatic cholestasis may be severe and medical treatment of this complication is often ineffective. We report a case of a 37 year-old male patient with sickle cell anemia, who developed liver failure and underwent successful orthotopic liver transplantation. Both pre and post-operatively, he was maintained on red cell transfusions. He remains stable with improved liver function 42 months post transplant. The role for orthotopic liver transplantation is not well defined in patients with sickle cell disease, and the experience remains limited. Although considerable challenges of post-transplant graft complications remain, orthotopic liver transplantation should be considered as a treatment option for sickle cell disease patients with end-stage liver disease who have progressed despite conventional medical therapy. An extended period of red cell transfusion support may lessen the post-operative complications.

    Currently, hematopoietic stem cell transplantation (HSCT) is the only curative option for patients with beta-thalassemia major, but liver iron overload in these patients will not decrease and hepatic fibrosis may still progress despite successful HSCT. Liver biopsy samples were taken from 14 patients (Out of 25 patients) who underwent HSCT. All patients met three criteria: negative HCV antibody, liver fibrosis in samples before HSCT and lack of regular treatment for iron overload after HSCT (Because patients did not consent to phlebotomy or they had not regular follow-up). We evaluated liver fibrosis and liver iron overload by a semi quantitative method, Perls' Prussian blue staining, before and after HSCT. HSCT was successful in all the patients. Liver iron overload did not change after transplant (P=0.61), but hepatic fibrosis progressed after transplant (P=0.01). In patients with beta thalassemia major who previously had some degree of liver fibrosis, HSCT alone cannot reduce liver iron overload and liver fibrosis will increase. We recommend that regardless of the amount of iron overload in patients with beta thalassemia major that have shown some degree of fibrosis in their liver biopsy before transplantation, appropriate steps should be taken to reduce iron overload as soon as possible after successful transplantation.

    Allogeneic hematopoietic cell transplantation (HCT) after nonmyeloablative conditioning for hematologic malignancies depends on graft-versus-tumor effects for eradication of cancer. Here, we estimated relapse risks according to disease characteristics. Between 1997 and 2006, 834 consecutive patients (median age, 55 years; range, 5-74 years) received related (n = 498) or unrelated (n = 336) HCT after 2 Gy total body irradiation alone (n = 171) or combined with fludarabine (90 mg/m(2); n = 663). Relapse rates per patient year (PY) at risk, corrected for follow-up and competing nonrelapse mortality, were calculated for 29 different diseases and stages. The overall relapse rate per PY was 0.36. Patients with chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) in remission (CR), low-grade or mantle cell non-Hodgkin lymphoma (NHL) (CR + partial remission [PR]), and high-grade NHL-CR had the lowest rates (0.00-0.24; low risk). In contrast, patients with advanced myeloid and lymphoid malignancies had rates of more than 0.52 (high risk). Patients with lymphoproliferative diseases not in CR (except Hodgkin lymphoma and high-grade NHL) and myeloid malignancies in CR had rates of 0.26-0.37 (standard risk). In conclusion, patients with low-grade lymphoproliferative disorders experienced the lowest relapse rates, whereas patients with advanced myeloid and lymphoid malignancies had high relapse rates after nonmyeloablative HCT. The latter might benefit from cytoreductive treatment before HCT.

    Full Text Available We examined if transplantation of combined haploidentical hematopoietic stem cells (HSC and mesenchymal stem cells (MSC affected graft failure and graft-versus-host disease (GVHD in patients with severe aplastic anemia (SAA. Patients with SAA-I (N = 17 received haploidentical HSCT plus MSC infusion. Stem cell grafts used a combination of granulocyte colony-stimulating factor (G-CSF-primed bone marrow and G-CSF-mobilized peripheral blood stem cells of haploidentical donors and the culture-expanded third-party donor-derived umbilical cord MSCs (UC-MSCs, respectively. Reduced intensity conditioning consisted of fludarabine (30 mg/m2·d+cyclosphamide (500 mg/m2·d+anti-human thymocyte IgG. Transplant recipients also received cyclosporin A, mycophenolatemofetil, and CD25 monoclonal antibody. A total of 16 patients achieved hematopoietic reconstitution. The median mononuclear cell and CD34 count was 9.3×10(8/kg and 4.5×10(6/kg. Median time to ANC was >0.5×10(9/L and PLT count >20×10(9/L were 12 and 14 days, respectively. Grade III-IV acute GVHD was seen in 23.5% of the cases, while moderate and severe chronic GVHD were seen in 14.2% of the cases. The 3-month and 6-month survival rates for all patients were 88.2% and 76.5%, respectively; mean survival time was 56.5 months. Combined transplantation of haploidentical HSCs and MSCs on SAA without an HLA-identical sibling donor was safe, effectively reduced the incidence of severe GVHD, and improved patient survival.

    Background Allogeneic stem cell transplantation is a potential curative approach in patients with multiple myeloma.The very high transplant related mortality associated with standard allogeneic stem cell transplantation is currently the major limitation to wider use of this potentially curative treatment modality. The challenge for clinical investigators is to reduce the incidence of post-transplant complications for patients receiving autologous hematopoietic stem cell transplantion for multiple myeloma. In this study the toxicity and efficacy of modified myeloablative conditioning regimen followed by allogeneic stem cell transplantation was investigated in patients with multiple myeloma.Methods The conditioning regimen consisted of hydroxyurea, cytarabine, busulfan, cyclophosphamide, and semustine.Ten patients underwent allogeneic transplantation among them hydroxyurea (40 mg/kg) was administered twice on day -10 and cytarabine (2 g/m2) was given on day -9, busulfan was administered orally in four divided doses daily for 3 days (days -8 to -6). The dose of busulfan was 12 mg/kg in the protocol followed by cyclophosphamide intravenously over 1hour on days -5 and -4 (1.8 g/m2), and with semustine (Me-CCNU) 250 mg/m2 on day -3.Results Chimerism data were available on all patients and all patients achieved full donor chimerism without graft failure. Six patients had not acute graft-versus-host disease (GVHD, 36.4%; 95% CI:13.9%-38.6%). Two patients (18.2%) developed grade Ⅰ acute GVHD (95% CI:10.9%-35.9%) and grade Ⅱ acute GVHD occurred in one patient (9.1%;95% CI: 8.4%-32.3%). Severe grade Iva GVHD was seen in one patient, who died from acute GVHD. The incidence of chronic GVHD was 22.2% (95% CI: 11.7%-36.7%), among them one died of severe grade IV GVHD and one developed multiorgan failure on day +170; the treatment-related mortality was 22.0% (95% CI: 10.3%-34.1%). The overall 4-year survival rate was 67.8% (95% CI: 16.3%-46.7%). The estimated 4-year

    Posaconazole has been proven to be effective for antifungal prophylaxis in adults after hematopoietic stem cell transplantation (HSCT). Due to low gastrointestinal resorption of posaconazole suspension, bioavailability is impaired. Fatty food improves the uptake of posaconazole, but insufficient data on the pharmacokinetics of posaconazole in pediatric patients are available so far. The single-center analysis investigated 161 posaconazole serum concentrations in 27 pediatric patients after HSCT receiving 12 mg·kg BW(-1)·d(-1) posaconazole suspension depending on age, gender, and intestinal graft-versus-host (iGvHD) disease, and the influence of posaconazole on cyclosporine A plasma concentrations. To improve the uptake of posaconazole, one patient cohort received higher fat nutrition with the drug administration. A comparison of the regular nutrition and higher-fat nutrition groups revealed the following values: 31 (27.4%) versus 8 (16.7%) 2000 ng/ml. The mean posaconazole concentrations in patients with regular nutrition was 1123 ± 811 ng/ml and with higher-fat nutrition was 1191 ± 673 ng/ml. Posaconazole levels in patients with iGvHD were significantly lower (P = 0.0003) than in patients without GvHD. The majority of samples showed a sufficient posaconazole concentration above 700 ng/ml. Posaconazole levels were slightly higher in patients with higher-fat nutrition and significantly lower in patients with iGvHD. Cyclosporine A levels were not significantly higher during posaconazole administration.

  8. The kinetics of early T and B cell immune recovery after bone marrow transplantation in RAG-2-deficient SCID patients.

    Directory of Open Access Journals (Sweden)

    Atar Lev

    Full Text Available The kinetics of T and B cell immune recovery after bone marrow transplantation (BMT is affected by many pre- and post-transplant factors. Because of the profoundly depleted baseline T and B cell immunity in recombination activating gene 2 (RAG-2-deficient severe combined immunodeficiency (SCID patients, some of these factors are eliminated, and the immune recovery after BMT can then be clearly assessed. This process was followed in ten SCID patients in parallel to their associated transplant-related complications. Early peripheral presence of T and B cells was observed in 8 and 4 patients, respectively. The latter correlated with pre-transplant conditioning therapy. Cells from these patients carried mainly signal joint DNA episomes, indicative of newly derived B and T cells. They were present before the normalization of the T cell receptor (TCR and the B cell receptor (BCR repertoire. Early presentation of the ordered TCR gene rearrangements after BMT occurred simultaneously, but this pattern was heterogeneous over time, suggesting different and individual thymic recovery processes. Our findings early after transplant could suggest the long-term patients' clinical outcome. Early peripheral presence of newly produced B and T lymphocytes from their production and maturation sites after BMT suggests donor stem cell origin rather than peripheral expansion, and is indicative of successful outcome. Peripheral detection of TCR excision circles and kappa-deleting recombination excision circles in RAG-2-deficient SCID post-BMT are early markers of T and B cell reconstitution, and can be used to monitor outcome and tailor specific therapy for patients undergoing BMT.

    Background Whether the sequential treatment with bortezomib plus dexamethasone (BD) followed by autologous hematopoietic stem cell transplantation (ASCT) could extend the overall survival period in multiple myeloma patients is still not clear.Few large case studies about this therapeutics in multiple myeloma were reported in China.Our purpose was to assess the efficacy and adverse effects of sequential treatment with BD chemotherapy and ASCT in patients with multiple myeloma.Methods Fifty-three patients with newly diagnosed or relapsed/refractory multiple myeloma received BD as induction therapy before ASCT.Stem-cell mobilization was undertaken with cyclophosphamide 3-5 g/m2 plus granulocyte colony-stimulating factor 300 μg/d.Target yield was 2.0×106 CD34+ cells/kg.Conditioning for ASCT consisted of melphalan 200 mg/m2.Thalidomide and/or α-interferon was used as post-transplantation maintenance treatment.Results The BD chemotherapy before transplantation was effective in 86.7% of the 53 patients,including 22.6% with complete remission (CR),39.6% with near complete remission (nCR),and 24.5% with partial remission (PR).The best effect was achieved after two treatment courses.Most bortezomib-related adverse effects were classes 1-2.All patients were successfully mobilized after BD for autologous peripheral blood stem cell transplantation.The ASCT was effective in 96.3% of patients,including 49.1% with CR,32.1% with nCR,and 15.1% with PR.The CR rate was significantly increased (49.1% vs.22.6%,P <0.05) by sequential ASCT.Within 27 (range,6-53) months of follow-up,the efficacy of ASCT was maintained in 29 patients and further enhanced by post-transplantation maintenance treatment in four patients.Eleven patients died after transplantation.Among the patients undergoing BD/ASCT treatment,overall survival (OS) was significantly better in newly diagnosed patients in comparison to relapsed/refractory patients (P=0.046).Conclusions BD chemotherapy can

    2016-01-01

    Full Text Available Allogenic hematopoietic cell transplantation (HSCT is typically the preferred curative therapy for adult patients with acute myeloid leukemia, but its use has been reduced as a consequence of limited donor availability in the form of either matched-related donors (MRD or matched-unrelated donors (MUD. Alternative options such as unrelated umbilical cord blood (UCB transplantation and haploidentical HSCT have been increasingly studied in the past few decades to overcome these obstacles. A human leukocyte antigen- (HLA- haploidentical donor is a recipient’s relative who shares an exact haplotype with the recipient but is mismatched for HLA genes on the unshared haplotype. These dissimilarities pose several challenges to the outcomes of the patient receiving such a type of HSCT, including higher rates of bidirectional alloreactivity and graft failure. In the past 5 years, however, several nonrandomized studies have shown promising results in terms of graft success and decreased rates of alloreactivity, in part due to newer grafting techniques and graft-versus-host disease (GVHD prophylaxis. We present here a summary and review of the latest results of these studies as well as a brief discussion on the advantages and challenges of haploidentical HSCT.

    Full Text Available The article focuses on aspects of T. gondii reactivation/reinfection in patients undergoing allogeneic hematopoietic stem cell transplantation (alloHSCT. We have observed 297 patients who received conditioning therapy and allogeneic grafts due to different oncohematological or lymphoproliferative diseases (1 to 60 years old, at a mediane of 19 years. Conditioning regimens were either myeloablative (35%, or non-myeloablative (65%. DNA diagnostics of T. gondii was performed on a regular basis at 0 to 6 months post-HSCT. IgG and IgM antibodies against T. gondii were determined in 78 patients before HSCT, as well as in their donors. T. gondii DNA post-transplant proved to be positive in 13% of blood specimens, 9% of cerebrospinal liquor samples, 11% of bronchoalveolar cell lavages, and in 5% of urine sediments. In adolescent patients (10 to 14 years old, an increased prevalence of T. gondii was found in patients who received myeloablative treatment (p = 0.01. When assessing posttransplant dynamics of T. gondii, we have revealed distinct increase in the pathogen excretion within 1st month after HSCT (p = 0.03. Finally, initial presence of IgG antibodies against T. gondii in the patients was associated with lower incidence of the pathogen reactivation post-transplant.

    Full Text Available Phaeohyphomycosis is caused by a large, heterogenous group of darkly pigmented fungi. The presence of melanin in their cell walls is characteristic, and is likely an important virulence factor. These infections are being increasingly seen in a variety of clinical syndromes in both immunocompromised and normal individuals. Transplant patients are especially at risk due their prolonged immunosuppression. There are no specific diagnostic tests for these fungi, though the Fontana-Masson stain is relatively specific in tissue. They are generally seen in a worldwide distribution, though a few species are only found in specific geographic regions. Management of these infections is not standardized due to lack of clinical trials, though recommendations are available based on clinical experience from case reports and series and animal models. Superficial infections may be treated without systemic therapy. Central nervous system infections are unique in that they often affect otherwise normal individuals, and are difficult to treat. Disseminated infections carry a high mortality despite aggressive therapy, usually with multiple antifungal drugs. Considerable work is needed to determine optimal diagnostic and treatment strategies for these infections.

    Recipients of hematopoietic cell transplantation may be at risk for developing acute kidney injury (AKI), and this risk may be increased in patients who undergo transplantation for severe systemic sclerosis (SSc) due to underlying scleroderma renal disease. AKI after transplantation can increase treatment-related mortality. To better define these risks, we analyzed 91 patients with SSc who were enrolled in 3 clinical trials in the United States of autologous or allogeneic hematopoietic cell transplantation (HCT). Eleven (12%) of the 91 patients with SSc in these studies (8 undergoing autologous HCT, 1 undergoing allogeneic HCT, 1 pretransplantation, 1 given i.v. cyclophosphamide on a transplantation trial) experienced AKI, of whom 8 required dialysis and/or therapeutic plasma exchange. AKI injury in the 9 HCT recipients developed a median of 35 days (range, 0-90 days) after transplantation. Ten of 11 patients with AKI received angiotensin-converting enzyme inhibitor (ACE-I) therapy. The etiology of AKI was attributed to scleroderma renal crisis in 6 patients (including 2 with normotensive renal crisis), to AKI of uncertain etiology in 2 patients, and to AKI superimposed on scleroderma kidney disease in 3 patients. Eight of the 11 patients died, one each because of progression of SSc, multiorgan failure, gastrointestinal and pulmonary bleeding, pericardial tamponade and pulmonary complications, diffuse alveolar hemorrhage, pulmonary embolism, graft-versus-host disease, and malignancy. Limiting nephrotoxins, cautious use of corticosteroids, renal shielding during total body irradiation, strict control of blood pressure, and aggressive use of ACE-Is may be of importance in preventing renal complications after HCT for SSc.

    Full Text Available Over the past decade, invasive fungal infections (IFI have remained an important problem in patients undergoing allogeneic haematopoietic stem cell transplantation (Allo-HSCT. The optimal approach for prophylactic antifungal therapy has yet to be determined. We conducted a retrospective, bi-institutional comparative clinical study, and compared the efficacy and safety of micafungin 50mg/day (iv with those of fluconazole (400mg/day or itraconazole 200mg/day (iv as prophylaxis for adult patients with various haematological diseases receiving haplo-identical allogeneic stem cell transplantation (haplo. Overall, 99 patients were identified; 30 patients received micafungin, and 69 patients received fluconazole or itraconazole. After a median follow-up of 13 months (range: 5-23, Proven or probable IFIs were reported in 3 patients (10% in the micafungin group and 8 patients (12% in the fluconazole or itraconazole group. Fewer patients in the micafungin group had invasive aspergillosis (1 [3%] vs. 5 [7%], P=0.6. A total of 4 (13% patients in the micafungin group and 23 (33% patients in the fluconazole or itraconazole group received empirical antifungal therapy (P = 0.14. No serious adverse events related to treatment were reported by patients and there was no treatment discontinuation because of drug-related adverse events in both groups. Despite the retrospective design of the study and limited sample, it contributes reassuring data to confirm results from randomised clinical trials, and to define a place for micafungin in prophylaxis after haplo.

    POEMS syndrome is a rare para-neoplastic syndrome secondary to a plasma cell dyscrasia. Effective treatment can control the disease-related symptom complex. We describe the clinical outcome of autologous stem cell transplantation for patients with POEMS syndrome, determining the impact of patient- and disease-specific factors on prognosis. One hundred and twenty-seven patients underwent an autologous stem cell transplantation between 1997–2010 with a median age of 50 years (range 26–69 years). Median time from diagnosis to autologous stem cell transplantation was 7.5 months with 32% of patients receiving an autologous stem cell transplantation more than 12 months from diagnosis. Engraftment was seen in 97% patients and engraftment syndrome was documented in 23% of autologous stem cell transplantation recipients. Hematologic response was characterized as complete response in 48.5%, partial response in 20.8%, less than partial repsonse in 30.7%. With a median follow up of 48 months (95%CI: 38.3, 58.6), 90% of patients are alive and 16.5% of patients have progressed. The 1-year non-relapse mortality was 3.3%. The 3-year probabilities of progression-free survival and overall survival are 84% and 94%, respectively, with 5-year probabilities of progression-free survival and overall survival of 74% and 89%. In a cohort of graft recipients, detailed organ-specific symptom response demonstrated clear symptom benefit after autologous stem cell transplantation especially in relation to neurological symptom control. The data analyzed in this study demonstrate the clinical utility of autologous stem cell transplantation for patients with POEMS syndrome. PMID:27634201

    Full Text Available Abstract Background Aberrations of allelic replication timing are epigenetic markers observed in peripheral blood cells of cancer patients. The aberrant markers are non-cancer-type-specific and are accompanied by increased levels of sporadic aneuploidy. The study aimed at following the epigenetic markers and aneuploidy levels in cells of patients with haematological malignancies from diagnosis to full remission, as achieved by allogeneic stem cell transplantation (alloSCT. Methods TP53 (a tumor suppressor gene assigned to chromosome 17, AML1 (a gene assigned to chromosome 21 and involved in the leukaemia-abundant 8;21 translocation and the pericentomeric satellite sequence of chromosome 17 (CEN17 were used for replication timing assessments. Aneuploidy was monitored by enumerating the copy numbers of chromosomes 17 and 21. Replication timing and aneuploidy were detected cytogenetically using fluorescence in situ hybridization (FISH technology applied to phytohemagglutinin (PHA-stimulated lymphocytes. Results We show that aberrant epigenetic markers are detected in patients with hematological malignancies from the time of diagnosis through to when they are scheduled to undergo alloSCT. These aberrations are unaffected by the clinical status of the disease and are displayed both during accelerated stages as well as in remission. Yet, these markers are eradicated completely following stem cell transplantation. In contrast, the increased levels of aneuploidy (irreversible genetic alterations displayed in blood lymphocytes at various stages of disease are not eliminated following transplantation. However, they do not elevate and remain unchanged (stable state. A demethylating anti-cancer drug, 5-azacytidine, applied in vitro to lymphocytes of patients prior to transplantation mimics the effect of transplantation: the epigenetic aberrations disappear while aneuploidy stays unchanged. Conclusions The reversible nature of the replication aberrations may

    The transplant of haematopoyetic parent cells is on common way of treating haematological neoplasias and other types of immunological and tumoural disorders. The aggressive nature of the treatment, leading to peculiar nutritional and metabolic conditions in these patients, as well as the notable incidence of complications, have meant that nutritional support is included in the therapeutic armoury. As in other clinical situations, we are currently able to go beyond merely ensuring the necessary nutritional support. We can also influence the progress of the illness by means of the provision of specific substrates which interfere in a positive manner with the disturbed intermediate metabolism. Even more, in some of these substrates we can find a nutrient drug action.

    Hematopoietic stem cell transplantation (HSCT) is a widely practiced therapy for many life-threatening childhood disorders. The authors investigated the psychosocial effects of HSCT on siblings of pediatric HSCT patients (n = 44; 21 donors, 23 nondonors, ages 6 to 18 years). Donor siblings reported significantly more anxiety and lower self-esteem than did nondonors. Nondonors showed significantly more school problems. Approximately one third of all siblings reported moderate to severe posttraumatic stress. The study drew on the developmental theory of Erik Erikson and the psychosocial model of posttraumatic stress. As part of the study, the authors used the Measures of Psychosocial Development (MPD), a self-report measure based on Eriksonian constructs. The MPD was used to assess the psychosocial adjustment of 12 siblings who were adolescents (> or =13 years) at the time the study was conducted. In this article, findings are presented from the MPD as well as salient findings from the larger study.

    We enrolled 30 patients on a prospective phase II trial utilizing a total body irradiation (TBI)-based myeloablative preparative regimen (fludarabine 30 mg/m2/day × 3 days and TBI 150 cGy twice per day on day -4 to -1 [total dose 1200 cGy]) followed by infusion of unmanipulated peripheral blood stem cells from a haploidentical family donor (haplo). Postgrafting immunosuppression consisted of cyclophosphamide 50 mg/kg/day on days 3 and 4, mycophenolate mofetil through day 35, and tacrolimus through day 180. Median patient age was 46.5 years (range, 24 to 60). Transplantation diagnosis included acute myelogenous leukemia (n = 16), acute lymphoblastic leukemia (n = 6), chronic myelogenous leukemia (n = 5), myelodysplastic syndrome (n = 1), and non-Hodgkin's lymphoma (n = 2). Using the Dana Farber/Center for International Blood and Marrow Transplant Research/Disease Risk Index (DRI), patients were classified as low (n = 4), intermediate (n = 12), high (n = 11), and very high (n = 3) risk. All patients engrafted with a median time to neutrophil and platelet recovery of 16 and 25 days, respectively. All evaluable patients achieved sustained complete donor T cell and myeloid chimerism by day +30. Acute graft-versus-host disease (GVHD) grades II to IV and III and IV was seen in 43% and 23%, respectively. The cumulative incidence of chronic GVHD was 56% (severe in 10%). After a median follow-up of 24 months, the estimated 2-year overall survival (OS), disease-free survival (DFS), nonrelapse mortality, and relapse rate were 78%, 73%, 3%, and 24%, respectively. Two-year DFS and relapse rate in patients with low/intermediate risk disease was 100% and 0%, respectively, compared with 39% and 53% for patients with high/very high risk disease. When compared with a contemporaneously treated cohort of patients at our institution receiving myeloablative HLA-matched unrelated donor (MUD) transplantation (acute myelogenous leukemia [n = 17], acute lymphoblastic leukemia [n = 15

    Full Text Available Abstract Background Previous therapy with anthracyclines (ANT and conditioning regimen followed by hematopoietic stem cell transplantation (HSCT represents a high risk for development of cardiotoxicity. The aim of this study was to assess subclinical myocardial damage after HSCT using echocardiography and cardiac biomarkers - high sensitive cardiac troponin T (hs-cTnT and N-terminal pro-B-type natriuretic peptide (NT-proBNP and to identify patients at risk of developing clinical cardiotoxicity. Patients and methods Thirty-seven patients who were treated with allogeneic HSCT for hematologic diseases at median age of 28 years at time of HSCT were studied. Conditioning regimen included either chemotherapy without total body irradiation (TBI or combination of chemotherapy with TBI. Twenty-nine (78,3% patients were pretreated with ANT therapy. Cardiac biomarkers were serially measured before conditioning regimen and at days 1, 14 and 30 after HSCT. Cardiac systolic and diastolic functions were assessed before conditioning regimen and 1 month after HSCT by echocardiography. Results The changes in plasma NT-proBNP and hs-cTnT levels during the 30 days following the HSCT were statistically significant (P P Conclusions Elevations in both cardiac biomarkers were found before clinical signs of cardiotoxicity developed. Persistent elevations in NT-pro-BNP and hs-cTnT concentrations simultaneously for a period exceeding 14 days might be used for identification of patients at risk of developing cardiotoxicity and requiring further cardiological follow up.

    Comprehensive recommendations for maintenance therapy after autologous stem cell transplantation (ASCT) for patients with multiple myeloma (MM) have yet to be defined. Bortezomib has been utilized as maintenance therapy after ASCT, but data attesting to the safety and efficacy of this agent compared with lenalidomide in the post-ASCT setting are limited. Therefore, we retrospectively analyzed the outcomes of 102 patients with MM who received maintenance therapy with bortezomib after ASCT at Duke University's adult bone marrow transplant clinic between 2005 and 2015. Maintenance with bortezomib was initiated between 60 and 90 days after ASCT as a single agent 1.3 mg/m(2) once every 2 weeks (n = 92) or in combination with lenalidomide (10 mg/day) (n = 10). The median age at ASCT was 64 (range, 31 to 78). Of the 99 patients with molecular data available, 42% had high-risk cytogenetics (including d17p, t(4;14), +1q, and t(14;16) by fluorescein in situ hybridization). Overall, 46% of patients experienced side effects from maintenance therapy, with 31% of all patients experiencing peripheral neuropathy. In total, 2% of patients required discontinuation of bortezomib maintenance because of adverse events. No secondary malignancies were reported from the therapy. The median progression-free survival (PFS) for patients receiving maintenance therapy with bortezomib after ASCT was 36.5 months (95% confidence interval [CI], 21.3 to not available) and median overall survival was 72.7 months (95% CI, 63.9 to not available). The PFS of patients with high-risk cytogenetics was not statistically significantly different from those with standard-risk cytogenetics, suggesting that maintenance with bortezomib may help overcome the impact of high-risk cytogenetics on early progression. These results indicate that maintenance therapy with bortezomib represents a safe, well-tolerated, and efficacious option for patients with high-risk cytogenetics, renal insufficiency, an

    Full Text Available Background. Allogeneic haemopoietic stem cell transplant (Allo-HSCT is a specialised and costly intervention, associated with significant morbidity and mortality. It is used to treat a broad range of paediatric conditions. South Africa (SA is an upper middle-income country with limitations on healthcare spending. The role of paediatric Allo-HSCT in this setting is reviewed. Objectives. To review paediatric patients who underwent Allo-HSCT at the Groote Schuur Hospital/University of Cape Town Private Academic Hospital transplant unit in Cape Town, South Africa, and received post-transplant care at Red Cross War Memorial Children’s Hospital, over the period January 2006 - December 2014 in respect of indications for the transplant, donor sources, conditioning regimens, treatment-related morbidity and overall survival (OS. Methods. A retrospective analysis of patient records was performed and a database was created in Microsoft Access. Descriptive analyses of relevant demographic, clinical and laboratory data were performed. Summary statistics of demographic and clinical parameters were derived with Excel. OS was calculated from the date of transplant to the date of an event (death or last follow-up using the Kaplan-Meier method in Statistica. Results. A total of 48 children received Allo-HSCT: 24 for haematological malignancies, 20 for non-oncological haematological conditions, 3 for immune disorders and 1 for adrenoleukodystrophy. There were 28 boys (median age 7.5 years and 20 girls (8.5 years. There were 31 sibling matched peripheral-blood stem cell (PBSC transplants and 1 maternal haploidentical PBSC transplant. Stem cells were mobilised from bone marrow into peripheral blood by administering granulocyte-colony stimulating factor to donors. PBSCs were harvested by apheresis. Eight patients received 10/10 HLA-matched grafts from unrelated donors. Six were PBSC grafts and 2 were bone marrow grafts. Three of the unrelated PBSC grafts were from

    Linezolid (LZD) is the first oxazolidinone antibiotic that is effective against drug-resistant gram-positive organisms. Hematological toxicities such as thrombocytopenia, anemia, and leukocytopenia are common in LZD therapy. However, LZD-induced pure red cell aplasia (PRCA) is very rare. A 56-year-old man with myelodysplastic syndrome underwent allogeneic bone marrow transplantation from a human leukocyte antigen-matched and ABO blood type-matched unrelated male donor. He had bacteremia caused by Staphylococcus epidermidis after engraftment of neutrophils and red blood cells. We first administered vancomycin, but then changed to intravenous LZD because of kidney damage. Two weeks after LZD therapy, the patient's hemoglobin and reticulocyte levels were 6.8 g/dL and 0.3%, respectively. Bone marrow examination revealed red blood cell aplasia (myeloid/erythroid ratio was 402). The patient showed rapid recovery of normal erythropoiesis within 2 weeks of LZD cessation. It is important to be aware of the hematological effects associated with LZD in the setting of stem cell transplantation,particularly for those with pre-existing myelosuppression, renal insufficiency, and those receiving concomitant drugs that produce bone marrow suppression. We advocate that a reticulocyte count be performed periodically for detecting bone marrow suppression, including PRCA, during LZD therapy.

    This commentary documents the increased number of stem cell-related research reports recently published in the cell transplantation field in the journal Cell Transplantation. The journal covers a wide range of issues in cell-based therapy and regenerative medicine and is attracting clinical and preclinical articles from around the world. It thereby complements and extends the basic coverage of stem cell physiology reported in Stem Cells and Development. Sections in Cell Transplantation cover neuroscience, diabetes, hepatocytes, bone, muscle, cartilage, skin, vessels, and other tissues, as well as tissue engineering that employs novel methods with stem cells. Clearly, the continued use of biomedical engineering will depend heavily on stem cells, and these two journals are well positioned to provide comprehensive coverage of these developments.

    Full Text Available Abstract Background Pediatric patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT often receive intravenous liposomal amphotericin B (L-AmB as antifungal prophylaxis. There are no guidelines for antifungal prophylaxis in children in this situation. Caspofungin (CAS, a broad-spectrum echinocandin, could be an effective alternative with lower nephrotoxicity than L-AmB. Methods We retrospectively analyzed the safety, feasibility, and efficacy of CAS in our center, and compared the results with L-AmB as antifungal monoprophylaxis in pediatric patients undergoing HSCT. 60 pediatric patients received L-AmB (1 or 3 mg/kg bw/day and another 60 patients received CAS (50 mg/m2/day as antifungal monoprophylaxis starting on day one after HSCT. The median ages of patients receiving L-AmB and CAS were 7.5 years and 9.5 years, respectively. Results No proven breakthrough fungal infection occurred in either group during the median treatment period of 23 days in the L-AmB group and 24 days in the CAS group. One patient receiving CAS developed probable invasive aspergillosis. During L-AmB treatment, potassium levels significantly decreased below normal values. Patients treated with L-AmB had more drug-related side effects and an increased need for oral supplementation with potassium, sodium bicarbonate and calcium upon discharge as compared with the CAS group. CAS was well-tolerated and safe in this cohort of immunocompromised pediatric patients, who underwent high-dose chemotherapy and HSCT. Conclusion Prophylactic CAS and L-AmB showed similar efficacy in this biggest cohort of pediatric patients after allogeneic HSCT reported, so far. A prospective randomized trial in children is warranted to allow for standardized guidelines.

    2011-06-01

    Full Text Available Interest in mismatched transplantation arises from the fact that a suitable one-haplotype mismatched donor is immediately available for virtually all patients, particularly for those who urgently need an allogenic transplant. Work on one haplotype-mismatched transplants has been proceeding for over 20 years all over the world and novel transplant techniques have been developed. Some centres have focused on the conditioning regimens and post transplant immune suppression; others have concentrated on manipulating the graft which may be a megadose of extensively T celldepleted or unmanipulated progenitor cells. Excellent engraftment rates are associated with a very low incidence of acute and chronic GVHD and regimen-related mortality even in patients who are over 50 years old. Overall, event-free survival and transplant-related mortality compare favourably with reports on transplants from sources of stem cells other than the matched sibling.

  16. Life-Threatening Adenovirus Infections in the Setting of the Immunocompromised Allogeneic Stem Cell Transplant Patients

    Directory of Open Access Journals (Sweden)

    Cedar J. Fowler

    2010-01-01

    Full Text Available A single institution case series of adenovirus infections after allogeneic hematopoietic stem cell transplantation is presented to highlight the consideration for adenovirus infections as an etiology in patients with rapid hepatic or other sudden organ deterioration in the setting of apparent GVHD stabilization. The series also highlights that survival is limited with these infections often due in part to concomitant opportunistic infections. In addition, the pathophysiological events, such as GVHD and hepatic dysfunction, may complicate the clinical picture and delay therapy of an opportunistic infection. This is particularly true for adenoviral infections as they also have a distinct clinical picture in immunocompromised patients when compared to immune competent patients. Adenovirus infections also have the additional challenge that its treatment, cidofovir, has associated toxicities that can delay its administration. Recent developments has yielded an assay that can be used in the early detection and for serial determinations of adenovirus in patients with advanced GVHD, as well as a new therapeutic agent currently undergoing clinical trials.

    Background Bloodstream infections (BSI) remain a frequent complication during the pre-engraftment period after hematopoietic stem cell transplantation (HSCT), resulting in high mortality rates. This study evaluated risk factors for mortality in hematopoietic stem cell transplant recipients with BSI in the pre-engraftment period. Methods This prospective case control study was performed at the Center of Hematology and Bone Marrow Transplantation in Minsk, Republic of Belarus. Data relating to patient age and gender, date and type of transplantation, conditioning chemotherapy regimen, microorganisms isolated from blood, and antibacterial therapy were prospectively collected from all hematopoietic stem cell recipients with microbiologically proven cases of BSI in the pre-engraftment period. The primary outcome was all-cause 30-day mortality after onset of febrile neutropenia. Results A total of 135 adult patients with microbiologically proven BSI after HSCT were studied, with 65.2% of cases caused by gram-negative microorganisms and 21.5% by non-fermenting bacteria. Inadequate empiric antibacterial therapy and isolation of carbapenem-resistant non-fermenting gram-negative bacteria (Acinetobacter baumannii and Pseudomonas aeruginosa) were independently associated with increased all-cause 30-day mortality in these patients. Conclusion The risk factors for mortality in adult patients with BSI in the pre-engraftment period after HSCT were inadequacy of empirical antibacterial therapy and isolation of carbapenem-resistant A. baumannii or P. aeruginosa.

    Efficacy of reduced-intensity stem-cell transplantation (RIST) for acute lymphoblastic leukemia (ALL) was investigated in 33 patients (median age, 55 years). RIST sources comprised 20 HLA-identical related donors, five HLA-mismatched related, and eight unrelated donors. Six patients had undergone previous transplantation. Disease status at RIST was first remission (n=13), second remission (n=6), and induction failure or relapse (n=14). All patients tolerated preparatory regimens and achieved neutrophil engraftment (median, day 12.5). Acute and chronic graft-versus-host disease (GVHD) developed in 45 and 64%, respectively. Six patients received donor lymphocyte infusion (DLI), for prophylaxis (n=1) or treatment of recurrent ALL (n=5). Nine patients died of transplant-related mortality, with six deaths due to GVHD. The median follow-up of surviving patients was 11.6 months (range, 3.5-37.3 months). The 1-year relapse-free and overall survival rates were 29.8 and 39.6%, respectively. Of the 14 patients transplanted in relapse, five remained relapse free for longer than 6 months. Cumulative rates of progression and progression-free mortality at 3 years were 50.9 and 30.4%, respectively. These findings suggest the presence of a graft-versus-leukemia effect for ALL. RIST for ALL is worth considering for further evaluation.

    Full Text Available We transplanted 47 patients with Fanconi anemia using an alternative source of hematopoietic cells. The patients were assigned to the following groups: group 1, unrelated bone marrow (N = 15; group 2, unrelated cord blood (N = 17, and group 3, related non-sibling bone marrow (N = 15. Twenty-four patients (51% had complete engraftment, which was not influenced by gender (P = 0.87, age (P = 0.45, dose of cyclophosphamide (P = 0.80, nucleated cell dose infused (P = 0.60, or use of anti-T serotherapy (P = 0.20. Favorable factors for superior engraftment were full HLA compatibility (independent of the source of cells; P = 0.007 and use of a fludarabine-based conditioning regimen (P = 0.046. Unfavorable factors were > or = 25 transfusions pre-transplant (P = 0.011 and degree of HLA disparity (P = 0.007. Intensity of mucositis (P = 0.50 and use of androgen prior to transplant had no influence on survival (P = 0.80. Acute graft-versus-host disease (GVHD grade II-IV and chronic GVHD were diagnosed in 47 and 23% of available patients, respectively, and infections prevailed as the main cause of death, associated or not with GVHD. Eighteen patients are alive, the Kaplan-Meyer overall survival is 38% at ~8 years, and the best results were obtained with related non-sibling bone marrow patients. Three recommendations emerged from the present study: fludarabine as part of conditioning, transplant in patients with <25 transfusions and avoidance of HLA disparity. In addition, an extended family search (even when consanguinity is not present seeking for a related non-sibling donor is highly recommended.

    Full Text Available The current report describes two renal transplant recipients who presented with sporotrichosis. In addition, the authors review the general aspects of sporotrichosis in renal transplant recipients reported in the literature. Sporotrichosis is a rare fungal infection in transplant patients and has been reported primarily in renal transplant recipients not treated with antifungal prophylaxis. Extracutaneous forms of sporotrichosis without skin manifestations and no previous history of traumatic injuries have been described in such patients and are difficult to diagnose. Renal transplant recipients with sporotrichosis described in the present report were successfully treated with antifungal therapy including amphotericin B deoxycholate, lipid amphotericin B formulations, fluconazole and itraconazole.

    Full Text Available Although sickle cell anemia and sickle cell disease produce a variety of functional renal abnormalities they uncommonly cause end stage renal failure. Renal transplantation has been a successful alternative for the treatment of the rare terminal chronic renal failure with outcomes comparable with non-sickle recipients. This approach, however, has not been often described on patients with renal failure associated with SC hemoglobinopathy. Here we report the outcomes of two patients with chronic renal failure due to SC hemoglobinopathies who underwent renal transplantation. At the time of the transplantation they were both severely anemic and had frequent vasoocclosive pain crises. Both patients evolved with good allograft function, near normal hematological parameters, and very rare pain crisis, thirteen and eight years after transplant. These cases illustrate that terminal renal failure due to SC hemoglobinopathy can be successfully managed by renal transplantation and satisfactory long-term results are achievable not only in terms of renal allograft function but also of their hematological condition.Embora a anemia falciforme e as síndromes falciformes freqüentemente causem várias alterações funcionais renais, não é comum a insuficiência renal terminal. Nestes casos, o transplante renal é uma alternativa que se acompanha de resultados comparáveis aos obtidos em receptores sem hemoglobinopatias. Esta estratégia terapêutica tem sido, no entanto, pouco relatada para portadores de hemoglobinopatia SC. Este relato descreve a evolução de dois pacientes portadores de hemoglobinopatia SC que foram submetidos ao transplante renal. No momento do transplante ambos apresentavam severa anemia e crises dolorosas freqüentes. Os pacientes evoluíram com boa função do enxerto, parâmetros hematológicos quase normais e praticamente assintomáticos do ponto de vista da hemoglobinopatia, treze e oito anos após o transplante. Estes casos ilustram

    Bloodstream infection (BSI) is a significant problem after cord blood transplantation (CBT). However, little information has been reported on BSI after reduced-intensity CBT (RI-CBT). We retrospectively reviewed the medical records of 102 patients. The median age of the patients was 55 years (range, 17-79 years). Preparative regimens comprised fludarabine 125 to 150 mg/m 2 , melphalan 80 to 140 mg/m 2 , or busulfan 8 mg/kg and total body irradiation 2 to 8 Gy. Prophylaxis against graft-versus-host disease comprised cyclosporin or tacrolimus. BSI developed within 100 days of RI-CBT in 32 patients. The cumulative incidence of BSI was 25% at day 30 and 32% at day 100. The median onset was day 15 (range, 1-98 days). Causative organisms included Pseudomonas aeruginosa (n = 12), Staphylococcus epidermidis (n = 11), Staphylococcus aureus (n = 6), Enterococcus faecium (n = 4), Enterococcus faecalis (n = 4), Stenotrophomonas maltophilia (n = 4), and others (n = 7). Of the 32 patients with BSI, 25 (84%) died within 100 days after RI-CBT. BSI was the direct cause of death in 8 patients (25%). Univariate analysis failed to identify any significant risk factors. BSI clearly represents a significant and fatal complication after RI-CBT. Further studies are warranted to determine clinical characteristics, identify patients at high risk of BSI, and establish therapeutic strategies.

    Purpose: Approximately 5% to 20% of patients who undergo total body irradiation (TBI) in preparation for hematopoietic cell transplantation (HCT) can develop extramedullary (EM) relapse. Whereas total marrow and lymphoid irradiation (TMLI) provides a more conformally targeted radiation therapy for patients, organ sparing has the potential to place the patient at a higher risk for EM relapse than TBI. This study evaluated EM relapse in patients treated with TMLI at our institution. Methods and Materials: Patients eligible for analysis had been enrolled in 1 of 3 prospective TMLI trials between 2006 and 2012. The TMLI targeted bones, major lymph node chains, liver, spleen, testes, and brain, using image-guided tomotherapy with total dose ranging from 12 to 15 Gy. Results: A total of 101 patients with a median age of 47 years were studied. The median follow-up was 12.8 months. Incidence of EM relapse and bone marrow (BM) relapse were 12.9% and 25.7%, respectively. Of the 13 patients who had EM relapse, 4 also had BM relapse, and 7 had EM disease prior to HCT. There were a total of 19 EM relapse sites as the site of initial recurrence: 11 soft tissue, 6 lymph node, 2 skin. Nine of these sites were within the target region and received ≥12 Gy. Ten initial EM relapse sites were outside of the target region: 5 sites received 10.1 to 11.4 Gy while 5 sites received <10 Gy. Pretransplantation EM was the only significant predictor of subsequent EM relapse. The cumulative incidence of EM relapse was 4% at 1 year and 11.4% at 2 years. Conclusions: EM relapse incidence was as frequent in regions receiving ≥10 Gy as those receiving <10 Gy. EM relapse rates following TMLI that included HCT regimens were comparable to published results with regimens including TBI and suggest that TMLI is not associated with an increased EM relapse risk.

    Autoimmune hemolytic anemia (AIHA) is a recognized complication of hematopoietic stem cell transplantation (HSCT); it is often refractory to treatment and carries a high mortality. To improve understanding of the incidence, risk factors, and clinical outcome of post-transplantation AIHA, we analyzed 533 patients who received allogeneic HSCT, and we identified 19 cases of AIHA after HSCT (overall incidence, 3.6%). The median time to onset, from HSCT to AIHA, was 202 days. AIHA was associated with HSCT from unrelated donors (hazard ratio [HR], 5.28; 95% confidence interval [CI], 1.22 to 22.9; P = .026). In the majority (14 of 19; 74%) of AIHA patients, multiple agents for treatment were required, with only 9 of 19 (47%) patients achieving complete resolution of AIHA. Patients with post-transplantation AIHA had a higher overall mortality (HR, 2.48; 95% CI, 1.33 to 4.63; P = .004), with 36% (4 of 11 cases) of deaths attributable to AIHA.

    The successful transplantation of human materials such as organs, tissues and cells into patients does not only depend on the benefits, but also on the mitigation of risks. To gain insight into recent publications on risks associated with the process of transferring human materials from donor to recipient we performed a horizon scan by reviewing scientific literature and news websites of 2011 on this subject. We found there is ample information on how extended donor criteria, such as donor age, affect the survival rates of organs or patients. Interestingly, gender mismatch does not appear to be a major risk factor in organ rejection. Data on risks of donor tumor transmission was very scarce; however, risk categories for various tumor types have been suggested. In order to avoid rejection, a lot of research is directed towards engineering tissues from a patient's own tissues and cells. Some but not all of these developments have reached the clinic. Developments in the field of stem cell therapy are rapid. However, many hurdles are yet to be overcome before these cells can be applied on a large scale in the clinic. The processes leading to genetic abnormalities in cells differentiated from stem cells need to be identified in order to avoid transplantation of aberrant cells. New insights have been obtained on storage and preservation of human materials, a critical step for success of their clinical use. Likewise, quality management systems have been shown to improve the quality and safety of human materials used for transplantation.

    Changes in genomic DNA methylation associated with cancer include global DNA hypomethylation and gene-specific hyper- or hypomethylation. We have previously identified a genetic variant in the MTHFR gene involved in the methylation pathway which confers risk for the development of squamous cell carcinoma (SCC) in renal transplant patients. This genetic variant has also been discovered to confer SCC risk in nontransplant patients with low folate status.

    In this prospective, observational study, we sought to investigate the incidence, risk factors, and outcomes of central venous catheter-associated infection in 56 patients admitted for hematopoietic stem cell transplantation. In multivariate analysis, we found a 7-fold higher risk of central line-associated bloodstream infection with central venous catheter insertion in the internal jugular vein as compared with the subclavian access. Patients with central line-associated bloodstream infection had a higher incidence of acute renal failure.

    TP53 gene deletion is associated with poor outcomes in multiple myeloma (MM). We report the outcomes of patients with MM with and without TP53 deletion who underwent immunomodulatory drug (IMiD) and/or proteasome inhibitor (PI) induction followed by autologous hematopoietic stem cell transplant (auto-HCT). We identified 34 patients with MM and TP53 deletion who underwent IMiD and/or PI induction followed by auto-HCT at our institution during 2008-2014. We compared their outcomes with those of control patients (n = 111) with MM without TP53 deletion. Median age at auto-HCT was 59 years in the TP53-deletion group and 58 years in the control group (P = 0.4). Twenty-one patients (62%) with TP53 deletion and 69 controls (62%) achieved at least partial remission before auto-HCT (P = 0.97). Twenty-three patients (68%) with TP53 deletion and 47 controls (42%) had relapsed disease at auto-HCT (P = 0.01). Median progression-free survival was 8 months for patients with TP53 deletion and 28 months for controls (P TP53 deletion and 56 months for controls (P TP53 deletion (hazard ratio 3.4, 95% confidence interval 1.9-5.8, P TP53 deletion and relapsed disease at the time of auto-HCT are independent predictors of progression.

    2010-03-01

    Full Text Available Abstract The human immunodeficiency virus type 1 (HIV-1 coreceptor use and viral evolution were analyzed in blood samples from an HIV-1 infected patient undergoing allogeneic stem cell transplantation (SCT. Coreceptor use was predicted in silico from sequence data obtained from the third variable loop region of the viral envelope gene with two software tools. Viral diversity and evolution was evaluated on the same samples by Bayesian inference and maximum likelihood methods. In addition, phenotypic analysis was done by comparison of viral growth in peripheral blood mononuclear cells and in a CCR5 (R5-deficient T-cell line which was controlled by a reporter assay confirming viral tropism. In silico coreceptor predictions did not match experimental determinations that showed a consistent R5 tropism. Anti-HIV directed antibodies could be detected before and after the SCT. These preexisting antibodies did not prevent viral rebound after the interruption of antiretroviral therapy during the SCT. Eventually, transplantation and readministration of anti-retroviral drugs lead to sustained increase in CD4 counts and decreased viral load to undetectable levels. Unexpectedly, viral diversity decreased after successful SCT. Our data evidence that only R5-tropic virus was found in the patient before and after transplantation. Therefore, blocking CCR5 receptor during stem cell transplantation might have had beneficial effects and this might apply to more patients undergoing allogeneic stem cell transplantation. Furthermore, we revealed a scenario of HIV-1 dynamic different from the commonly described ones. Analysis of viral evolution shows the decrease of viral diversity even during episodes with bursts in viral load.

    Patients undergoing hematopoietic cell transplantation (HCT) can have complications that require management in the intensive care unit (ICU). We conducted a retrospective study of patients undergoing HCT between 2007 and 2011 with admission to the ICU. We analyzed 97 patients, with an average age of 37 (range, 15 to 68). The main indications for HCT were hematologic malignancies (84%, n = 82). Ninety percent (n = 87) received myeloablative conditioning. Thirty-one percent were admitted (autologous transplant recipients 15%, allogeneic transplant recipients 34%, and umbilical cord blood [UCB] transplant recipients 48%) with an average length of stay of 19 days (range, 1 to 73 days). The average time between transplantation and transfer was 15 days. The main causes of admission were acute respiratory failure (63%) and septic shock (20%). ICU mortality was 20% for autologous transplantations and 64% for allogeneic transplantations (adult donor and UCB combined). On average, patients died 108 days after the transplantation (range, 4 to 320 days). One-year overall survival, comparing patients entering the ICU with those never admitted, was 16% versus 82% (P < .0001) for allogeneic transplantations (adult donor and UCB combined) and 80% versus 89% (P = not significant) for autologous transplantations. Acute graft-versus-host disease was significantly associated with death in ICU after UCB HCT. ICU support is satisfactory in about one half of patients admitted, characterized by a short and medium term prognosis not as unfavorable as has been previously reported.

    Sinusoidal obstruction syndrome, previously known as veno-occlusive disease (VOD/SOS), is a complication in patients undergoing haemopoietic stem cell transplantation (HSCT). Severe VOD/SOS, including progression to multi-organ failure, has resulted in a mortality of greater than 80%. Defibrotide's varying pharmacological actions, particularly on endothelial cells, make it is a useful agent to consider for prophylaxis and treatment of VOD/SOS. Barriers to its routine use include the high acquisition cost and the fact that neither the oral or parenteral formulations are licensed products in many countries at this time. This review summarises available literature on the use of defibrotide in the management of VOD/SOS. Publications consist predominantly of single centre cohort studies and case series. Available evidence indicates that defibrotide is effective in the management of VOD/SOS. Using defibrotide prophylaxis should also be considered, especially in the paediatric setting, where there are available results from a large, open label, randomized controlled trial. Patient outcome data from the larger studies and compassionate programs can inform consensus recommendations on dosing regimen and criteria for the treatment of VOD/SOS with defibrotide in the adult population. The reviewed literature indicates an effective and safe dose for treatment is 25mg/kg/day, continued for at least 14days or until complete response is achieved. Further studies are required to determine the optimal dose and duration of treatment in both paediatric patients and adults. Recent recommendations and a phase 3 trial using historical controls indicate that defibrotide should be included as a pharmacotherapy option in protocols guiding management of VOD/SOS.

    Based on the representative articles in recent years, the different mechanisms of decitabine on immune regulation in patients with acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (HSCT) are summarized. Decitabine improves the expression of WT1 gene to stimulate specific cytotoxic T cells which can enhance graft versus leukemia effect (GVL) and improve the expression of FOXP3 gene to stimulate regulatory T cells so as to inhibit the acute graft versus host disease (GVHD). Through the above-mentimed mechanisms, decitabine can improve both therapeutic effect and quality of life in the patients with AML after allogeneic HSCT.

    Recipients of SOT and HSCT constitute a risk group for becoming ill with tuberculosis (TB). The prevalence of active TB in patients undergoing TOS is higher than in patients undergoing HSCT, probably for the shortest period of immunosuppression of the latter. Most TB cases occur in transplant patients by reactivation of latent infection after immunosuppression, which occurs most often within the first year post-transplant, causing graft loss and in some cases death. Relevant variables to assess the risk of TB infection in a transplant recipient are the medical history of donor and recipient, images, microbiology and tuberculin tests and interferon gamma levels. PPD is routinely performed in the donor and in the recipient before transplantation. If PPD is > 5 mm in the recipient or > 10 mm in the donor, it is neccesary to exclude active TB (pulmonary and renal) (A2).

    Hematopoietic cell transplantation (HCT) is a procedure that can significantly influence the socioeconomic wellbeing of patients, caregivers and their families. Among 30 allogeneic HCT recipients and their caregivers enrolled on a pilot study evaluating the feasibility of studying financial impact of HCT, 16 agreed to participate in the long-term phase, completed a baseline questionnaire and received phone interviews at 6, 12, 18 and 24 months post HCT. Analyses showed that by 2 years post HCT, 54% of patients who previously contributed to household earnings had not returned to work and 80% of patients/caregivers reported transplant as having moderate to great impact on household income. However, patients' levels of confidence in their abilities to meet household financial obligations increased from baseline to 2 years. A relatively large proportion of patients reported inability to pay for medical care through this time period. Case studies demonstrated that patients' individual perceptions of the financial impact of HCT varies considerably, regardless of actual income. We demonstrate the feasibility of conducting a study to evaluate the financial impact of allogeneic HCT through 2 years post transplantation. Some patients/caregivers continue to experience a significant long-term financial burden after this procedure. Our study lays the foundation for a larger evaluation of patient/caregiver financial burden associated with HCT.

    A female patient diagnosed with acute myelocytic leukemia M5a (AML-M5a) relapsed 986 days after her allogeneic peripheral blood stem cell transplantation (allo-PBSCT) from an unrelated male donor with matched human leukocyte antigen (HLA).Three re-induction chemotherapies were administered,and partial remission was achieved.The patient was given repetitive infusion of cytokine-induced killer (CIK) cells expanded from recipient peripheral mononuclear cells of full donor chimerism due to loss of contact of quondam donor for donor lymphocyte infusion (DLI) and rejection of second transplantation.The patient achieved complete cytogenetical remission.This strategy might overcome the obstacle of donor unavailability and present an appealing new therapeutic alternative to donor-recruited adoptive immunotherapy for relapsed disease at post-transplantation.

    Full Text Available Parasitic infections are rarely documented in hematopoietic stem cell transplant recipients. However, they may be responsible for fatal complications that are only diagnosed at autopsy. Increased awareness of the possibility of parasitic diseases both in autologous and allogeneic stem cell transplant patients is relevant not only for implementing preventive measures but also for performing an early diagnosis and starting appropriate therapy for these unrecognized but fatal infectious complications in hematopoietic transplant recipients. In this review, we will focus on parasitic diseases occurring in this population especially those with major clinical relevance including toxoplasmosis, American trypanosomiasis, leishmaniasis, malaria, and strongyloidiasis, among others, highlighting the diagnosis and management in hematopoietic transplant recipients.

    We conducted a nation-wide survey of 112 adult Japanese patients who underwent reduced-intensity stem cell transplantation (RIST) from 1999 to 2002. Underlying diseases included indolent (n=45), aggressive (n=58) and highly aggressive lymphomas (n=9). Median age of the patients was 49 years. A total of 40 patients (36%) had relapsed diseases after autologous stem cell transplantation and 36 patients (32%) had received radiotherapy. RIST regimens were fludarabine-based (n=95), low-dose total body irradiation-based (n=6) and others (n=11). Cumulative incidences of grade II-IV acute graft-versus-host disease (GVHD) and chronic GVHD were, respectively, 49 and 59%. Cumulative incidences of progression and progression-free mortality were 18 and 25%, respectively. With a median follow-up of 23.9 months, 3-year overall survival rates were 59%. A multivariate analysis identified three significant factors for progression, which are history of radiation (relative risk (RR) 3.45, confidential interval (CI) 1.12-10.0, P=0.03), central nervous system involvement (RR 6.25, CI 2.08-20.0, P=0.001) and development of GVHD (RR 0.28, CI 0.090-0.86, P=0.026). RIST may have decreased the rate of transplant-related mortality, and GVHD may have induced a graft-versus-lymphoma effect. However, whether or not these potential benefits can be directly translated into improved patient survival should be evaluated in further studies.

    Alternative graft sources (umbilical cord blood [UCB], matched unrelated donors [MUD], or mismatched unrelated donors [MMUD]) enable patients without a matched sibling donor to receive potentially curative hematopoietic cell transplantation (HCT). Retrospective studies demonstrate comparable outcomes among different graft sources. However, the risk and types of infections have not been compared among graft sources. Such information may influence the choice of a particular graft source. We compared the incidence of bacterial, viral, and fungal infections in 1781 adults with acute leukemia who received alternative donor HCT (UCB, n= 568; MUD, n = 930; MMUD, n = 283) between 2008 and 2011. The incidences of bacterial infection at 1 year were 72%, 59%, and 65% (P < .0001) for UCB, MUD, and MMUD, respectively. Incidences of viral infection at 1 year were 68%, 45%, and 53% (P < .0001) for UCB, MUD, and MMUD, respectively. In multivariable analysis, bacterial, fungal, and viral infections were more common after either UCB or MMUD than after MUD (P < .0001). Bacterial and viral but not fungal infections were more common after UCB than MMUD (P = .0009 and <.0001, respectively). The presence of viral infection was not associated with an increased mortality. Overall survival (OS) was comparable among UCB and MMUD patients with Karnofsky performance status (KPS) ≥ 90% but was inferior for UCB for patients with KPS < 90%. Bacterial and fungal infections were associated with poorer OS. Future strategies focusing on infection prevention and treatment are indicated to improve HCT outcomes.

    Limited clinical data are available to assess whether the sequencing of cyclophosphamide (Cy) and total body irradiation (TBI) changes outcomes. We evaluated the sequence in 1769 (CyTBI, n = 948; TBICy, n = 821) recipients of related or unrelated hematopoietic cell transplantation who received TBI (1200 to 1500 cGY) for acute leukemia from 2003 to 2010. The 2 cohorts were comparable for median age, performance score, type of leukemia, first complete remission, Philadelphia chromosome-positive acute lymphoblastic leukemia, HLA-matched siblings, stem cell source, antithymocyte globulin use, TBI dose, and type of graft-versus-host disease (GVHD) prophylaxis. The sequence of TBI did not significantly affect transplantation-related mortality (24% versus 23% at 3 years, P = .67; relative risk, 1.01; P = .91), leukemia relapse (27% versus 29% at 3 years, P = .34; relative risk, .89, P = .18), leukemia-free survival (49% versus 48% at 3 years, P = .27; relative risk, .93; P = .29), chronic GVHD (45% versus 47% at 1 year, P = .39; relative risk, .9; P = .11), or overall survival (53% versus 52% at 3 years, P = .62; relative risk, .96; P = .57) for CyTBI and TBICy, respectively. Corresponding cumulative incidences of sinusoidal obstruction syndrome were 4% and 6% at 100 days (P = .08), respectively. This study demonstrates that the sequence of Cy and TBI does not impact transplantation outcomes and complications in patients with acute leukemia undergoing hematopoietic cell transplantation with myeloablative conditioning.

    Although hematopoietic cell transplantation (HCT) is the only curative therapy for many advanced hematologic cancers, little is known about the financial hardship experienced by HCT patients nor the association of hardship with patient-reported outcomes. We mailed a 43-item survey to adult patients approximately 180 days after their first autologous or allogeneic HCT at 3 high-volume centers. We assessed decreases in household income; difficulty with HCT-related costs, such as need to relocate or travel; and 2 types of hardship: hardship_1 (reporting 1 or 2 of the following: dissatisfaction with present finances, difficulty meeting monthly bill payments, or not having enough money at the end of the month) and "hardship_2" (reporting all 3). Patient-reported stress was measured with the Perceived Stress Scale-4, and 7-point scales were provided for perceptions of overall quality of life (QOL) and health. In total, 325 of 499 surveys (65.1%) were received. The median days since HCT was 173; 47% underwent an allogeneic HCT, 60% were male, 51% were > 60 years old, and 92% were white. Overall, 46% reported income decline after HCT, 56% reported hardship_1, and 15% reported hardship_2. In multivariable models controlling for income, those reporting difficulty paying for HCT-related costs were more likely to report financial hardship (odds ratio, 6.9; 95% confidence interval, 3.8 to 12.3). Hardship_1 was associated with QOL below the median (odds ratio, 2.9; 95% confidence interval, 1.7 to 4.9), health status below the median (odds ratio, 2.2; 95% confidence interval, 1.3 to 3.6), and stress above the median (odds ratio, 2.1; 95% confidence interval, 1.3 to 3.5). In this sizable cohort of HCT patients, financial hardship was prevalent and associated with worse QOL and higher levels of perceived stress. Interventions to address patient financial hardship-especially those that ameliorate HCT-specific costs-are likely to improve patient-reported outcomes.

    Ronald Brand

    Full Text Available Allogeneic stem cell transplantation (ASCT from related or unrelated donors may cure patients with myelodysplastic syndromes (MDS, a heterogeneous group of clonal stem cell disorders. We analysed 384 elderly patients (55-69 years with advanced MDS who received either ASCT (n=247 and were reported to The European Group for Blood and Marrow Transplantation (EBMT or a non -transplant approach (n=137 reported to the Düsseldorf registry. Besides an attempt to answer the question of "comparison", the purpose of this work is to explain the difficulties in comparing a non-transplant with a transplant cohort, when death before transplant is likely but unknown and the selection of patients for transplant is based on assumptions. It shows which methods are almost always biased and that even the most sophisticated approaches crucially rely on clinical assumptions. Using the most appropriate model for our data, we derive an overall univariate non-significant survival disadvantage for the transplant cohort (HR: 1.29, p = 0.11. We show that such an "average" hazard ratio is however misleading due to non-proportionality of the hazards reflecting early treatment related mortality, the occurring of which is logically correlated with the interval between diagnosis and transplant creating a disproportional drop in the (reconstructed survival curve of the transplanted patients. Also in multivariate analysis (correcting for age > 60 (HR: 1.4, p = 0.02 and abnormal cytogenetics (HR: 1.46, p = 0.01, transplantation seems to be worse (HR: 1.39, p = 0.05 but only in the (incorrect but commonly applied model without time varying covariates. The long term (time depending hazard ratio is shown to be virtually 1 and overall survival is virtually identical in both groups. Nonetheless no conclusion can be reached from a clinical point of view without assumptions which are by their very nature untestable unless all patients would be followed from diagnosis.

    Background Umbilical cord blood (UCB) has grown substantially as an alternative source of hematopoietic stem cells for unrelated donor transplantation in both adult and pediatric patients.Our aim was to assess the leukemia-free survival (LFS) and some primary results,such as hematologic recovery,risk of graft-versus-host disease (GVHD),relapse,and long-term survival,after unrelated cord blood transplantation compared with the outcomes of transplantations from other unrelated graft source.Methods The clinical outcomes of 112 consecutive patients with acute leukemia who received umbilical cord blood (UCBT) as a primary unrelated stem cell source (n=38),bone marrow (UBMT n=28,transplanted before January 2003),or peripheral blood stem cells (UPBSCT n=46,transplanted after January 2003) between July 2000 and July 2008 were analyzed.Results Except that the patients were much younger in the UCBT group (median age,10.5 years in UCBT,30 years in UPBSCT,and 20 years in UBMT),other pre-transplant parameters,such as gender,diagnosis,and the phase of disease,were comparable.All patients received myeloablative regimens,primarily including BUCY; however,there was less antithymocyte globulin (ATG) used for the UBMT patients (2138 in UCBT,0/46 in UPBSCT,and 8/28 in UBMT did not use ATG,P=0.000).Significant delays in engraftment occurred after UCBT for both neutrophil cells and platelets.The cumulative allo-engraftment rates were also significantly lower (87.8% vs.97.8% vs.100% for WBC,P=0.000; 73.0% vs.97.5% vs.89.5% for PLT,P=0.000) for UCBT.The incidence of Grade 2-4 and 3-4 acute graft versus host disease (aGVHD) was much higher in the UBMT group but did not differ among the other groups (51% and 13.2%,40.2% and 10.5%,and 77.4% and 41.2%,respectively,for UCBT,UPBSCT,and UBMT,P=0.000).The occurrence of extensive chronic GVHD (cGVHD)was significantly decreased for recipients of UCBT (4%) compared with that of UPBSCT (39.1%) and UBMT (49.1%,P=0

    Liver transplantation has been remarkably effective in the treatment in patients with end-stage liver disease. However, disparity between solid-organ supply and increased demand is the greatest limitation, resulting in longer waiting times and increase in mortality of transplant recipients. This situation creates the need to seek alternatives to orthotopic liver transplantation.Hepatocyte transplantation or liver cell transplantation has been proposed as the best method to support patients. The procedure consists of transplanting individual cells to a recipient organ in sufficient quantity to survive and restore the function. The capacity of hepatic regeneration is the biological basis of hepatocyte transplantation. This therapeutic option is an experimental procedure in some patients with inborn errors of metabolism, fulminant hepatic failure and acute and chronic liver failure, as a bridge to orthotopic liver transplantation. In the Hospital La Fe of Valencia, we performed the first hepatocyte transplantation in Spain creating a new research work on transplant program.

    Haematopoietic stem cell transplantation (SCT) is used to treat a wide range of malignant and non-malignant haematological conditions, solid malignancies, and metabolic and autoimmune diseases. Although imaging has a limited role before SCT, it is important after transplantation when it may support the clinical diagnosis of a variety of complications. It may also be used to monitor the effect of therapy and to detect recurrence of the underlying disease if the transplant is unsuccessful. We present a pictorial review of the imaging of patients who have undergone SCT, based upon 15 years experience in a large unit performing both adult and paediatric transplants.

    In a cohort of β-Thalassemia (β-Thal) transplanted with haploidentical-HSCT we identified one transplanted patient characterized by persistent mixed chimerism (PMC) for several months after HSCT. In this unique β-Thal patient we assessed the donor engraftment overtime after transplantation, the potential loss of the non-shared HLA haplotype, and the presence of CD49b+LAG-3+ T regulatory type 1 (Tr1) cells, previously demonstrated to be associated with PMC after HLA-related HSCT for β-Thal. The majority of the patient's erythrocytes were of donor origin, whereas T cells were initially mostly derived from the recipient, no HLA loss, but an increased frequency of circulating Tr1 cells were observed. For the first time, we showed that when the proportion of residual donor cells decreases, the frequency of CD49b+LAG-3+ Tr1 cells declines, reaching the levels present in healthy subjects. These findings confirm previous results obtained in transplant related settings for β-Thal, and supported the central role of Tr1 cells in promoting and maintaining PMC after allo-HSCT.

    Full Text Available In a phase I/IIa open-label and nonrandomized controlled clinical trial, we sought to assess the safety and neurological effects of human neural stem/progenitor cells (hNSPCs transplanted into the injured cord after traumatic cervical spinal cord injury (SCI. Of 19 treated subjects, 17 were sensorimotor complete and 2 were motor complete and sensory incomplete. hNSPCs derived from the fetal telencephalon were grown as neurospheres and transplanted into the cord. In the control group, who did not receive cell implantation but were otherwise closely matched with the transplantation group, 15 patients with traumatic cervical SCI were included. At 1 year after cell transplantation, there was no evidence of cord damage, syrinx or tumor formation, neurological deterioration, and exacerbating neuropathic pain or spasticity. The American Spinal Injury Association Impairment Scale (AIS grade improved in 5 of 19 transplanted patients, 2 (A → C, 1 (A → B, and 2 (B → D, whereas only one patient in the control group showed improvement (A → B. Improvements included increased motor scores, recovery of motor levels, and responses to electrophysiological studies in the transplantation group. Therefore, the transplantation of hNSPCs into cervical SCI is safe and well-tolerated and is of modest neurological benefit up to 1 year after transplants. This trial is registered with Clinical Research Information Service (CRIS, Registration Number: KCT0000879.

    2012-10-01

    Full Text Available Abstract Background Pediatric patients undergoing hematopoietic stem cell transplantation (HSCT are at high risk of acquiring fungal infections. Antifungal prophylaxis shortly after transplantation is therefore indicated, but data for pediatric patients under 12 years of age are scarce. To address this issue, we retrospectively assessed the safety, feasibility, and initial efficacy of prophylactic posaconazole in children. Methods 60 consecutive pediatric patients with a median age of 6.0 years who underwent allogeneic HSCT between August 2007 and July 2010 received antifungal prophylaxis with posaconazole in the outpatient setting. 28 pediatric patients received an oral suspension at 5 mg/kg body weight b.i.d., and 32 pediatric patients received the suspension at 4 mg/kg body weight t.i.d. The observation period lasted from start of treatment with posaconazole until its termination (maximum of 200 days post-transplant. Results Pediatric patients who received posaconazole at 4 mg/kg body weight t.i.d. had a median trough level of 383 μg/L. Patients who received posaconazole at 5 mg/kg body weight b.i.d. had a median trough level of 134 μg/L. Both regimens were well tolerated without severe side effects. In addition, no proven or probable invasive mycosis was observed. Conclusion Posaconazole was a well-tolerated, safe, and effective oral antifungal prophylaxis in pediatric patients who underwent high-dose chemotherapy and HSCT. Posaconazole at a dosage of 12 mg/kg body weight divided in three doses produced consistently higher morning trough levels than in patients who received posaconazole 5 mg/kg body weight b.i.d. Larger prospective trials are needed to obtain reliable guidelines for antifungal prophylaxis in children after HSCT.

    Epstein-Barr virus-related post-transplant lymphoproliferative disorders are recognized as a significant cause of morbidity and mortality in patients undergoing hematopoietic stem cell transplantation. To better define current understanding of post-transplant lymphoproliferative disorders in stem cell transplant patients, and to improve its diagnosis and management, a working group of the Sixth European Conference on Infections in Leukemia 2015 reviewed the literature, graded the available quality of evidence, and developed evidence-based recommendations for diagnosis, prevention, prophylaxis and therapy of post-transplant lymphoproliferative disorders exclusively in the stem cell transplant setting. The key elements in diagnosis include non-invasive and invasive methods. The former are based on quantitative viral load measurement and imaging with positron emission tomography; the latter with tissue biopsy for histopathology and detection of Epstein-Barr virus. The diagnosis of post-transplant lymphoproliferative disorder can be established on a proven or probable level. Therapeutic strategies include prophylaxis, preemptive therapy and targeted therapy. Rituximab, reduction of immunosuppression and Epstein-Barr virus-specific cytotoxic T-cell therapy are recommended as first-line therapy, whilst unselected donor lymphocyte infusions or chemotherapy are options as second-line therapy; other methods including antiviral drugs are discouraged.

    DC is an inherited bone marrow failure syndrome mainly characterized by nail dystrophy, abnormal skin pigmentation, and oral leukoplakia. Bone marrow failure is the most common cause of death in patients with DC. Because previous results of HSCT with a myeloablative regimen were disappointing, we used a reduced-intensity conditioning regimen for two patients with classic DC, and one patient with cryptic DC who harbored the TERT mutation. Graft sources included two mismatched-related bone marrow (BM) donors and one unrelated BM donor. Successful engraftment was achieved with few regimen-related toxicities in all patients. They were alive 10, 66, and 72 months after transplantation, respectively. Long-term follow-up is crucial to determine the late effects of our conditioning regimen.

    Caregivers of patients receiving allogeneic hematopoietic stem cell transplants (Allo-HSCT) serve a pivotal role in patient care but experience high stress, anxiety, and depression as a result. We theorized that a stress management adapted for Allo-HSCT caregivers would reduce distress compared to treatment as usual (TAU). From 267 consecutive caregivers of Allo-HSCT patients approached, 148 (mean=53.5 years, 75.7% female) were randomized to either psychosocial intervention (n=74) or TAU (n=74). Eight 1-on-1 stress management sessions delivered across the 100 day post-transplant period focused on understanding stress, changing role(s) as caregiver, cognitive behavioral stress management, pacing respiration, and identifying social support. Primary outcomes included perceived stress (psychological) and salivary cortisol awakening response (CAR) (physiological). Randomized groups were not statistically different at baseline. Mixed models analysis of covariance (intent-to-treat) showed that intervention was associated with significantly lower caregiver stress 3 months post-transplant (Mean=20.0, CI95=17.9-22.0) compared to TAU (Mean=23.0, CI95=21.0-25.0) with an effect size (ES) of 0.39 (p=0.039). Secondary psychological outcomes, including depression and anxiety, were significantly reduced with ESs of 0.46 and 0.66 respectively. Caregiver CAR did not differ from non-caregiving controls at baseline and was unchanged by intervention. Despite significant caregiving burden, this psychosocial intervention significantly mitigated distress in Allo-HSCT caregivers. PMID:25961767

    OBJECTIVE: The motor symptoms of Parkinson's disease (PD) can be improved by cell transplantation,which has caught general attention from the field of the therapy for PD recently. In this paper, we summarize the cell-based therapy for PD.DATA SOURCES: A search for English literature related to the cellular transplantation of PD from January 1979to July 2006 was conducted in Medline with the key words of "Parkinson's disease, cell transplantation,embryonic stem cells, neural stem cells".STUDY SELECTTON: Data were checked in the first trial, and literatures about PD and cell transplantation were selected. Inclusive criteria: ① PD; ② Cell transplantation. Exclusive criteria: repetitive researches.DATA EXTRACTTON: A total of 100 papers related to cellular transplant and PD were collected and 41literatures were in accordance with the inclusive criteria.DATA SYNTHESIS: PD is a neural degeneration disease that threatens the health of the aged people, and most traditional therapeusis cannot delay its pathological proceeding. Cell transplantation is becoming popular as a new therapeutic tool, and the cells used to transplant mainly included dopamine-secreting cells, fetal ventral mesencephalic cells, embryonic stem cells and neural stem cells up to now. Animal experiment and clinical test demonstrate that cell transplantation can relieve the motor symptoms of Parkinson's disease obviously, but there are some problems need to be solved.CONCLUSTON: Cell transplantation has visible therapeutic efficacy on PD. Following the improvement of technique, and we have enough cause to credit that cell therapy may cure PD in the future.

    The purpose of this study was to evaluate the feasibility and efficacy of allogeneic hematopoietic stem cell transplantation with a reduced-intensity regimen (RIST) in patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). In all, 36 patients (median age 55 years) underwent RIST from an HLA-matched related donor between September 1999 and December 2002. The diagnoses included AML (n=14), leukemia evolving from MDS (n=10), and MDS (refractory anemia with excess blasts n=6, refractory anemia n=6). The RIST regimen consisted of purine analog (cladribine or fludarabine)/busulfan, with or without antithymocyte globulin. The regimen was well tolerated, and 34 patients achieved durable engraftment and most achieved remission after RIST. A total of 17 patients developed grade II-IV acute GVHD, and 27 developed chronic GVHD. Eight patients relapsed, and five of them received antithymocyte globulin (ATG) as part of the preparative regimen. A total of 12 patients died (four disease progression, six transplantation-related complications, and two others). Estimated 1-year disease-free survival (DFS) in low- and high-risk groups was 85 and 64%, respectively. We conclude that RIST can be performed safely in elderly patients with myeloid malignancies, and has therapeutic potential for those who fail conventional chemotherapy. In view of the significant association between GVHD or ATG and DFS, defined management of GVHD following RIST should become a major target of clinical research.

    Stem cells can differentiate into a variety of cells to replace dead cells or to repair damaged tissues. Recent evidence indicates that stem cells are involved in the pathogenesis of transplant arteriosclerosis, an alloimmune initiated vascular stenosis that often results in transplant organ failure. Although the pathogenesis of transplant arteriosclerosis is not yet fully understood, recent developments in stem cell research have suggested novel mechanisms of vascular remodeling in allografts. For example, stem cells derived from the recipient may repair damaged endothelial cells of arteries in transplant organs. Further evidence suggests that stem cells or endothelial progenitor cells may be released from both bone marrow and non-bone marrow tissues. Vascular stem cells appear to replenish cells that died in donor vessels. Concomitantly, stem/progenitor cells may also accumulate in the intima, where they differentiate into smooth muscle cells. However, several issues concerning the contribution of stem cells to the pathogenesis of transplant arteriosclerosis are controversial, eg, whether bone marrow-derived stem cells can differentiate into smooth muscle cells that form neointimal lesions of the vessel wall. This review summarizes recent research on the role of stem cells in transplant arteriosclerosis, discusses the mechanisms of stem cell homing and differentiation into mature endothelial and smooth muscle cells, and highlights the controversial issues in the field.

    Conventionally, serum protein electrophoresis (SPE) and serum immunofixation electrophoresis (IFE) are used as primary methods to diagnose and monitor multiple myeloma (MM). Recently, serum-free light chain (FLC) assay has been incorporated into hematological screening programs for myeloma. The purpose of this study is to compare the performance of the three methods in monitoring MM patients after autologous stem cell transplantation (ASCT). SPE, serum IFE and serum FLC assay were performed on 38 MM patients who underwent ASCT. In total, four patients had unexpected protein bands (UPBs) and 13 patients had relapsed after ASCT. Our results indicate that IFE is more sensitive than SPE and FLC assay in detection of UPBs and relapse. The results of IFE may provide useful information in advance of patient relapse.

    Allogeneic HSCT is the only curative treatment for SCD. In this study, we estimated the number of Saudi patients with SCD who are candidates for HSCT. We used the presence of overt stroke, recurrent ACS, and frequent severe pain crisis as indications for HSCT. We calculated the frequencies of these complications among a Saudi SCD cohort of 376 patients with SCD, 250 from SW and 126 from Eastern (E) provinces. We found that 59 (23.6%) of SW patients were transplant candidates compared to 22 (17.4%) from E province. It is estimated that about 61 000 patients with SCD live in Saudi Arabia. Thus, the projected number of Saudi patients with SCD who are candidates for HSCT is 10 536 patients. Of those, 2148 are children. The burden of SCD on HSCT centers in Saudi Arabia is substantial and is difficult currently to meet the demand. We recommend recruiting/training more transplant physicians and nurses, expand current capacity of centers if feasible, and open new transplant centers to make HSCT a practical therapeutic option for patients with severe SCD in Saudi Arabia.

    The incidence of invasive fungal infection (IFI) has increased considerably over the past 20 years, and transplant recipients are at especially high risk for fungal infections owing to their overall immunosuppressed condition. Organ transplantation procedures were incorporated as a therapeutic option for many patients who lacked the normal functions of organs such as the heart, liver, kidney, lung, pancreas and small bowel. The prevalence of IFI in solid organ transplant (SOTR) patients ranges from 5 to 50% in kidney and liver transplants, respectively. In bone marrow transplant (BMT) patients, IFI are major causes of morbidity and mortality due to the protracted neutropenic period and graft-versus-host disease. Candida spp. and Aspergillus spp. account for >80% of fungal episodes in both SOTR and BMT. The development of new immunosuppressive agents, new prophylaxis strategies (as pre-emptive therapy) and the improvement in surgical techniques led to increase survival of transplant recipients. In this session, a clear and concise update of the recent advances in the laboratory diagnosis of candidiasis and aspergillosis in this kind of patients was presented. However, we still need to establish more rapid, sensitive and specific methods for IFI diagnosis. Representatives of the 'Subcomision de Infecciones en el Paciente Neutropenico y Transplantado (SIPNYT)' de la Sociedad Argentina de Infectologia (SADI), presented the results of an unusual multicenter study both retrospective and descriptive studies of IFI in SOTR and BMT patients in Argentina. In addition, a study of IFI in 1,861 SOTR patients from four centers and the analysis of IFI in 2,066 BMT patients from all 12 BMT centers from Argentina was presented. From these studies it can be concluded that 'all transplant recipients are not the same' and that they should be stratified according to their different risk degrees in order to determine the best prophylaxis and treatment strategies.

    2015-01-01

    A survey within Italian haematopoietic stem cell transplant (HSCT) programmes was performed, in order to obtain a snapshot of nutritional support (NS) in patients undergoing HSCT. The primary objective was to verify whether an evidence-based practice (EBP) approach to NS was implemented in HSCT centres. A multicentre survey was performed by questionnaire, covering the main areas of NS (screening, treatment planning, monitoring, nutritional counselling, and methods of nutritional support). The results indicated a significant variation between clinical practice and evidence-based guidelines in terms of clinical pathways, decision-making, and care provision regarding NS. Further research is required to identify reasons for the limited application of EBP and measures that may be undertaken to address such issues. Development of a multidisciplinary educational programme in order to raise awareness of the issue should be undertaken.

    We evaluated the outcomes and associated prognostic factors in 233 patients undergoing allogeneic hematopoietic cell transplantation (HCT) for primary myelofibrosis (MF) using reduced intensity conditioning (RIC). Median age at HCT was 55 years. Donors were: matched sibling donor (MSD), 34%; HLA-well-matched unrelated donors (URD), 45%; and partially/mismatched URD, 21%. Risk stratification according to Dynamic International Prognostic Scoring System (DIPSS): low, 12%; intermediate-1, 49%; intermediate-2, 37%; and high, 1%. The probability of survival at 5-years was 47% (95% CI 40–53). In a multivariate analysis, donor type was the only independent factor associated with survival. Adjusted probabilities of survival at 5-years for MSD, well matched URD and partially matched/mismatched URD were 56% (95% CI 44–67), 48% (95% CI 37–58), and 34% (95% CI 21–47), respectively (p=0.002). Relative risks (RR) for NRM for well-matched URD and partially matched/mismatched URD were 3.92 (p=0.006) and 9.37 (p<0.0001), respectively. A trend towards increased NRM (RR 1.7, p=0.07) and inferior survival (RR 1.37, p=0.10) was observed in DIPSS-intermediate-2/high-risk patients compared to DIPSS-low/intermediate-1 risk patients. RIC HCT is a potentially curative option for patients with MF, and donor type is the most important factor influencing survival in these patients. PMID:24161923

    Full Text Available Leukemic blasts overexpress immunogenic antigens, so-called leukemia-associated antigens like the receptor for hyaluronan acid-mediated motility (RHAMM. Persistent RHAMM expression and decreasing CD8+ T-cell responses to RHAMM in the framework of allogeneic stem cell transplantation or chemotherapy alone might indicate the immune escape of leukemia cells. In the present study, we analyzed the expression of RHAMM in 48 patients suffering from acute myeloid leukemia (AML and myelodysplastic syndrome (MDS. Furthermore, we correlated transcripts with the clinical course of the disease before and after treatment. Real-time quantitative reverse transcriptase polymerase chain reaction was performed from RNA of peripheral blood mononuclear cells. T cell responses against RHAMM were assessed by tetramer staining (flow cytometry and enzyme-linked immunospot (ELISPOT assays. Results were correlated with the clinical outcome of patients. The results of the present study showed that almost 60% of the patients were RHAMM positive; specific T-cells recognizing RHAMM could be detected, but they were nonfunctional in terms of interferon gamma or granzyme B release as demonstrated by ELISPOT assays. Immunotherapies like peptide vaccination or adoptive transfer of RHAMM-specific T cells might improve the immune response and the outcome of AML/MDS patients.

    The purpose of this study was to report our experience with administration of plerixafor for the mobilization of hematopoietic stem cells (HSCs) in patients with refractory or recurrent germ cell tumors who were candidates for salvage therapy with high-dose chemotherapy and HSC transplantation and for whom mobilization of HSCs had not been achieved by standard therapies. This retrospective and observational study selected patients who were eligible for autologous HSC transplantation (AHSCT) and received plerixafor after failure of HSC mobilization by granulocyte colony-stimulating factor (G-CSF). A total of 5 patients (4 male and 1 female), aged 19-41 years (mean age, 29.6 years) were initially selected. Four patients (80%) achieved an adequate HSC mobilization with plerixafor and subsequently received high-dose chemotherapy followed by HSC transplantation. In these patients, the number of CD34(+) cells collected following plerixafor mobilization was 1.8×10(6)-10.3×10(6) cells/kg, with a peak CD34(+) cell count of 7.0-32.0 cells/μl. Following HSC infusion, these 4 patients achieved a neutrophil count of >0.5×10(3)/mm(3) and a platelet count of >20,000/μl between days 10 and 14. Therefore, patients with high-risk germ cell tumors eligible for AHSCT who are refractory to mobilization by G-CSF, may benefit from the use of plerixafor, possibly to the same extent as patients with lymphoma and multiple myeloma.

    Full Text Available Systemic fungal infections are a major cause of infection-related mortality in patients with hematologic malignancies. This report addresses the case of an adolescent patient with acute lymphoblastic leukemia who underwent three allogeneic hematopoietic stem cell transplantations and developed pulmonary aspergillosis. Combination therapy with liposomal amphotericin B (L-AmB, 3 mg/kg bw/day and caspofungin (CAS, 50 mg/day during the first allogeneic hematopoietic stem cell transplantation (HSCT improved the pulmonary situation. After shifting the antifungal combination therapy to oral voriconazole (2 × 200 mg/day and CAS, a new pulmonal lesion occurred alongside the improvements in the existing pulmonary aspergillosis. An antifungal combination during a second HSCT with L-AmB (3 mg/kg bw/day and CAS showed an improvement in the pulmonary aspergillosis. A combination therapy with CAS and L-AmB (1 mg/kg bw/day during the third HSCT led once again to progress the pulmonary aspergillosis, after increasing the L-AMB to 3 mg/kg bw/day for recovery. The presented case provides an example of how, despite severe immunosuppression, a combination of antifungal drugs administered intravenously at therapeutic dosages may be more efficient than either intravenous monotherapy or combinations of intravenous and oral antifungals in selecting pediatric and adolescent patients with proven fungal infections.

    Objective To compare the efficiency and safety of intracoronary transplantation of peripheral blood stem cells (PBSC) between elderly and younger patients with heart failure after myocardial infarction (MI). Methods Twenty-five patients with heart failure after MI were divided into aged group(≥60 years,n=13) and non-aged group (<60years,n=12) to receive intracoronary PBSC transplantation (PBSCT) following bone marrow cells mobilized by granulocyte colony-stimulating factor (G-CSF). Clinical data including coronary lesion characteristic, left ventricular shape, infarct region area and cardiac function, as well as adverse side effects between the two groups were compared. Left ventricular function was evaluated before and 6 months after the treatment by single photon emission computed tomography (SPECT). Results At 6 months, the left ventricular ejection fraction (LVEF) and 6 minute walk test (6MWT)distance increased, while the left ventricular diastolic diameter (LVDd) decreased significantly in both groups. There were no significant difference between the two groups in absolute change in the cardiac function parameters. Conclusions The present study demonstrated that autologous intracoronary PBSCT might be safe and feasible for both old and younger patients with heart failure after MI and left ventricular function is significantly improved.

    In this retrospective study, 209 patients with malignant disease were analyzed for levels of T-cell receptor excision circles (TRECs) for the first 24 months after allogeneic stem cell transplantation. CD3(+) cells were separated by direct antibody-coupled magnetic beads, followed by DNA extraction according to a standard protocol. The δRec-ψJα signal joint TREC was measured with real-time quantitative PCR. Patients were grouped based on malignant disease: chronic myeloid leukemia, chronic lymphatic leukemia, acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), and myelodysplastic syndrome (MDS). Patients were further subdivided based on TREC levels below (low-TREC) or above (high-TREC) median at each time point. TREC levels were then correlated to relapse incidence and relapse-free survival (RFS). For patients with AML, low TREC levels 2 months post-transplantation were correlated to high relapse incidence at 5 years (Pleukemia, high TREC levels were correlated with improved RFS (Pafter allogeneic hematopoietic stem cell transplantation.

    2013-01-01

    Hematopoietic stem-cell transplantation is the treatment of choice for severe combined immunodeficiency (SCID). Despite successful T-cell engraftment in transplanted patients, B-cell function is not always achieved; up to 58% of patients require immunoglobulin therapy after receiving haploidentical transplants. We report 2 half-sibling males with X-linked γ-chain SCID treated with different sources of stem cells. Sibling 1 was transplanted with T-cell-depleted haploidentical maternal bone marrow and sibling 2 was transplanted with 7/8 human leukocyte antigen-matched unrelated umbilical cord blood. Both patients received pretransplant conditioning and posttransplant graft-versus-host-disease prophylaxis. B-cell engraftment and function was achieved in sibling 1 but not in sibling 2. This disparate result is consistent with a review of 19 other SCID children who received cord blood transplants. B-cell function, as indicated by no need for immunoglobulin therapy, was restored in 42% of patients given haploidentical transplants and in 68% of patients given matched unrelated donor transplants compared with 80% of patients given cord blood transplants. Cord blood is an alternative source of stem cells for transplantation in children with SCID and has a higher likelihood of B-cell reconstitution.

    The purpose of this study was to determine the long-term safety of transplanting human fetal neuroretinal cells (14 to 18 week gestational age) into a series of patients with advanced retinitis pigmentosa (RP). After obtaining informed consent, both hosts and mothers of donors were screened for transmissible diseases. Pre- and postoperative clinical exams, visual acuity, electroretinograms, and fluorescein angiograms were performed and visual field testing was attempted in each case. Surgically, an anterior approach through pars plana ciliaris was used. A retinotomy was performed in the paramacular area and a two-function cannula was introduced into the subretinal space to deliver a suspension of donor cells. The cell suspension carried approximately 4000 cells/microl; the volume injected did not exceed 150 microl. The patients were examined for periods ranging from 12 to 40 months posttransplantation. To date, no evidence of inflammation, infection, or overt rejection of the graft was noted in the host eye, neither was any change observed in the contralateral, unoperated eye. In conclusion, neuroretinal cells were injected into the subretinal space of 14 patients with advanced RP with no clinical appearance of detrimental effects at the time of surgery or up to 40 months postinjection except in 1 patient who developed retinal detachment. This sets the stage for a phase II clinical trial to determine the possible beneficial effects of this procedure in patients blinded by degenerative retinal disease.

    The treatment of patients with chronic myelomonocytic leukemia (CMML) with transplant has not been optimized. We retrospectively reviewed the data for 83 consecutive patients with CMML (47 with CMML-1/2 and 36 with CMML progressed to acute myeloid leukemia) who received an allogeneic stem cell transplant (allo-SCT) at our institution between April 1991 and December 2013 to identify factors associated with improved survival and determine whether treatment with hypomethylating agents before transplant improves progression-free survival (PFS). The median age of the cohort was 57 years. Seventy-eight patients received induction treatment before transplant, with 37 receiving hypomethylating agents and 41 receiving cytotoxic chemotherapy. Patients treated with a hypomethylating agent had a significantly lower cumulative incidence of relapse at 3 years post-transplant (22%) than those treated with other agents (35%; P = .03), whereas treatment-related mortality at 1 year post-transplant did not significantly differ between the groups (27% and 30%, respectively; P = .84). The lower relapse rate resulted in a significantly higher 3-year PFS rate in patients treated with a hypomethylating agent (43%) than in those treated with other agents (27%; P = .04). Our data support the use of hypomethylating agents before allo-SCT for patients with CMML to achieve morphologic remission and improve PFS of these patients. Future studies are needed to confirm these findings.

    Full Text Available Haploidentical hematopoietic stem-cell transplantation is an alternative transplant strategy for patients without an HLA-matched donor. Still, only half of patients who might benefit from transplantation are able to find an HLA-matched related or unrelated donor. Haploidentical donor is readily available for many patients in need of immediate stem-cell transplantation. Historical experience with haploidentical stem-cell transplantation has been characterised by a high rejection rate, graft-versus-host disease, and transplant-related mortality. Important advances have been made in this field during the last 20 years. Many drawbacks of haploidentical transplants such as graft failure and significant GVHD have been overcome due to the development of new extensive T cell depletion methods with mega dose stem-cell administration. However, prolonged immune deficiency and an increased relapse rate remain unresolved problems of T cell depletion. New approaches such as partial ex vivo or in vivo alloreactive T cell depletion and posttransplant cell therapy will allow to improve immune reconstitution in haploidentical transplants. Results of unmanipulated stem-cell transplantation with using ATG and combined immunosuppression in mismatched/haploidentical transplant setting are promising. This paper focuses on recent advances in haploidentical hematopoietic stem-cell transplantation for hematologic malignancies.

    Hepatic cell transplantation consists of grafting already differentiated cells such as hepatocytes. Human hepatocytes are viable and functionally active. Liver cell transplantation is carried out by means of a 3-step method: isolation of hepatocytes from donor liver rejected for orthotopic transplantation, preparing a cell suspension for infusion and, finally, hepatocytes are implanted into the recipient. There are established protocols for the isolation of human hepatocytes from unused segments of donor livers, based on collagenase digestion of cannulated liver tissue at 37 degrees C. The hepatocytes can be used fresh or cryopreserved. Cryopreservation of isolated human hepatocytes would then be available for planned use. In cell transplant, the important aspects are: infusion route, number of cells, number of infusions and viability of the cells. The cells are infused into the patient through a catheter inserted via portal vein or splenic artery. Liver cell transplantation allows liver tissue to be used that would, otherwise, be discarded, enabling multiple patients to be treated with hepatocytes from a single tissue donor.

    Full Text Available Sickle cell anemia is one of the most common hemoglobinopathies in the worldwide. Sickle cell anemia characterized by crises and organ failure develops over time. Myeloablative stem cell transplantation is curative but it has been performed in children younger than 16 years of age. Modest modifications in the conditioning regimen and supportive care have improved outcome such that the majority of children with a suitable HLA-matched sibling donor can expect a cure from this approach. But nonmyeloablative protocols are crucial for the future of Hematopoietic Stem-Cell Transplantation for older sickle cell anemia patients with organ failure. A protocol for nonmyeloablative allogeneic hematopoietic stem-cell transplantation that includes total-body irradiation and treatment with alemtuzumab and sirolimus can achieve stable, mixed donor–recipient chimerism. Stem cell transplantation is recommended in the presence of HLA-matched siblings in patients at risk.

    Objectives Bone-marrow stem-cell transplantation has been shown to improve cardiac function in patients with acute myocardial infarction (AMI), but the safety of intracoronory infusion of autologous peripheral blood stem-cell (PBSCs) in patients with AMI is unknown. For this reason, we observe the feasibility and safety of PBSCs transplantation by intracoronory infusion in such patients. Methods 41 patients with AMI were allocated to receive granulocyte colony-stimulating factor (GCSF: Filgrastim, 300μg) with the dose of 300μg~600μg/day to mobilize the stem cell, and the duration of applying G-CSF was 5 days. On the sixth day, PBSCs were separated by Baxter CS 3000 blood cel 1 separator into suspend liquid 57 ml. Then the suspend liquid was infused into the infarct related artery (IRA)by occluding the over the wire balloon and infusing artery through balloon center lumen. In the process of the intracoronary infusion of PBSCs, the complications should be observed, which were arrhythmias including of bradycardia, sinus arrest or atrial ventricular block,premature ve. ntricular beats , ven~icular tachycardia,ventricular fibrillation; and hypotention, etc. Results There were total 10 cases with complications during the intracoronary infusion of PBSCs. The incidence of complications was 24.4% ( 10/41 ), including bradycardia was 2.4 % (1/41), sinus arrest or atrial ventricular block was 4.0% (2/41), ventricular fibrillation was 2.4 %(1/41), hypotentionwas 14.6 % (6/41).Conclusions In patients with AMI, intracoronary infusion of PBSCs is feasible and safe.

    Non-tuberculous mycobacterial (NTM) disease is a relatively rare cause of neutropenic fever in patients with hematologic malignancies. During the neutropenic period, performing invasive procedures for microbiological or pathological confirmation is difficult. In addition, the optimal treatment duration for NTM disease in patients with leukemia, especially prior to stem cell transplantation (SCT), has not been documented. Therefore, we report a case of pneumonia with necrotizing lymphadenitis caused by Mycobacterium kansasii diagnosed during chemotherapy being performed for acute myeloid leukemia. The radiologic findings were similar to those of invasive fungal pneumonia; however, a bronchoalveolar washing fluid culture confirmed that the pathogen was M. kansasii. After 70 days from starting NTM treatment, allogeneic SCT was performed without any complications. The patient fully recovered after 12 months of NTM treatment, and neither reactivation of M. kansasii infection nor related complications were reported.

    Invasive fungal infections (IFIs) frequently occur and are associated with high morbidity and mortality in patients with hematologic malignancies (HMs) and hematopoietic stem cell transplant (HSCT) recipients. Early diagnosis of IFI in these patients facilitates prompt institution of therapy and leads to improved clinical outcomes. This article reviews widely used methodologies for diagnosing IFIs in patients with HM and HSCT recipients. Advantages and limitations of radiologic studies; microbiologic and histopathologic techniques; fungal biomarker assays, including those for galactomannan antigen and β-(1-3)-D-glucan; and molecular assays that are available to establish an early diagnosis of clinically relevant invasive fungal infections are discussed. Recommendations are provided regarding effective use of these methodologies in clinical practice.

    Twenty patients with resistant and relapsed Hodgkin's disease were included into this investigation. The treatment effectiveness and regimen-related toxicity of BEAM-protocol were evaluated. Stem cell transplantation (SCT) was carried out either as bone marrow transplantation (BMT) in 11 patients or peripheral blood stem cell transplantation (PBSCT) in 9 patients. A comparison of the results pointed to a significant decrease in neutropenia duration, fewer blood transfusions needed and shorter stay in hospital in the PBSCT group. Complete remission was observed in 90% of patients of the SCT group, 91%-in BMT and 89%-PBSCT groups. It was found that high-dose chemotherapy followed by SCT is more effective in the treatment of resistant and relapsed Hodgkin's disease and, in certain situations, it is a treatment of choice. As to the toxicity of BEAM-protocol, it does not exceed those of the other chemotherapy modalities used in SCT.

    Under the long-term monitoring of patients treated in childhood or adolescence for cancer, we present in this article the long-term monitoring and therefore possible effects of patients who underwent allergenic hematopoietic stem cell transplantation. This article is based on a collaborative effort organized by the French Society of Bone Marrow Transplantation and Cell Therapy (SFGM-TC), which took place during the 4th day of allograft harmonization practices. Patients affected are children and young adults (0-25 years). We defined the monitoring effects beyond 1 year post-transplant. Our recommendations are based on a literature review, in line with the Leucémie Enfant Adulte (LEA) study cohort of long-term monitoring of patients treated for hematological malignancies in childhood, grafted or not. It became important to determine the nature of problems, their risk factors, frequency and monitoring necessary to implement for their detection. We will not address the therapeutic management of sequelae.

    This report retrospectively analyzed the outcome of 91 patients aged 60 years or older with refractory/relapsed (R/R) classical Hodgkin's lymphoma (cHL) who underwent autologous stem cell transplantation (ASCT) between 1992 and 2013 and were reported to the French Society of Bone Marrow Transplantation and Cell Therapies registry. The median age at transplant was 63 years. The majority of patients exhibited disease chemosensitivity to salvage treatment (57 complete responses, 30 partial responses, 1 progressive disease and 3 unknown). The most frequent conditioning regimen consisted of BCNU, cytarabine, etoposide, melphalan (BEAM) chemotherapy (93%). With a median follow-up of 54 months, 5-year estimates of overall survival (OS) and progression free survival (PFS) for the entire group were 67 and 54%, respectively. Despite the missing data, in univariate analysis, the number of salvage chemotherapy lines (1-2 versus ⩾3) significantly influenced the OS, unlike the other prognostic factors (stage III-IV at relapse, disease status before ASCT and negative positron emission tomography (PET) scan) encountered in younger patients. In spite of its limitations, this retrospective study with a long-term follow-up suggests that ASCT is a valid treatment option for chemosensitive R/R cHL in selected elderly patients, with an acceptable rate of toxicity.

    Strategies to fill the huge gap in supply versus demand of human organs include bioartificial organs, growing humanized organs in animals, cell therapy, and implantable bioengineered constructs. Reproducing the complex relations between different cell types, generation of adequate vasculature, and immunological complications are road blocks in generation of bioengineered organs, while immunological complications limit the use of humanized organs produced in animals. Recent developments in induced pluripotent stem cell (iPSC) biology offer a possibility of generating human, patient-specific organs in non-human primates (NHP) using patient-derived iPSC and NHP-derived iPSC lacking the critical developmental genes for the organ of interest complementing a NHP tetraploid embryo. The organ derived in this way will have the same human leukocyte antigen (HLA) profile as the patient. This approach can be curative in genetic disorders as this offers the possibility of gene manipulation and correction of the patient's genome at the iPSC stage before tetraploid complementation. The process of generation of patient-specific organs such as the liver in this way has the great advantage of making use of the natural signaling cascades in the natural milieu probably resulting in organs of great quality for transplantation. However, the inexorable scientific developments in this direction involve several social issues and hence we need to educate and prepare society in advance to accept the revolutionary consequences, good, bad and ugly.

    The goal of this clinical trial was to assess the feasibility and safety of transplanting autologous bone marrow mononuclear cells into patients suffering severe embolic stroke. Major inclusion criteria included patients with cerebral embolism, age 20-75 years, National Institute of Health Stroke Scale (NIHSS) score displaying improvement of ≤ 5 points during the first 7 days after stroke, and NIHSS score of ≥ 10 on day 7 after stroke. Bone marrow aspiration (25 or 50 mL; N = 6 patients in each case) was performed 7-10 days poststroke, and bone marrow mononuclear cells were administrated intravenously. Mean total transplanted cell numbers were 2.5 × 10(8) and 3.4 × 10(8) cells in the lower and higher dose groups, respectively. No apparent adverse effects of administering bone marrow cells were observed. Compared with the lower dose, patients receiving the higher dose of bone marrow cells displayed a trend toward improved neurologic outcomes. Compared with 1 month after treatment, patients receiving cell therapy displayed a trend toward improved cerebral blood flow and metabolic rate of oxygen consumption 6 months after treatment. In comparison with historical controls, patients receiving cell therapy had significantly better neurologic outcomes. Our results indicated that intravenous transplantation of autologous bone marrow mononuclear cells is safe and feasible. Positive results and trends favoring neurologic recovery and improvement in cerebral blood flow and metabolism by cell therapy underscore the relevance of larger scale randomized controlled trials using this approach.

    Full Text Available Introduction. Multiple sclerosis (MS is an immunemediated disease of the central nervous system that affects young individuals and leads to severe disability. High dose immunoablation followed by autologous hemopoietic stem cell transplantation (AHSCT has been considered in the last 15 years as potentialy effective therapeutic approach for agressive MS. The most recent long-time follow-up results suggest that AHSCT is not only effective for highly aggressive MS, but for relapsing-remitting MS as well, providing long-term remission, or maybe even cure. We presented a 10- year follow-up of the first MS patient being treated by immunoablation therapy and AHSCT. Case report. A 27-year-old male experienced the first symptoms - intermitent numbness and paresthesia of arms and legs of what was treated for two years by psychiatrist as anxiety disorder. After he developed severe paraparesis he was admitted to the Neurology Clinic and diagnosed with MS. Our patient developed aggressive MS with frequent relapses, rapid disability progression and transition to secondary progressive form 6 years after MS onset [the Expanded Disability Status Scale (EDSS 7.0 Ambulation Index (AI 7]. AHSCT was performed, cyclophosphamide was used for hemopoietic stem cell mobilization and the BEAM protocol was used as conditionig regimen. No major adverse events followed the AHSCT. Neurological impairment improved, EDSS 6.5, AI 6 and during a 10-year followup remained unchanged. Brain MRI follow-up showed the absence of gadolinium enhancing lesions and a mild progression of brain atrophy. Conclusion. The patient with rapidly evolving, aggressive, noninflammatory MS initialy improved and remained stable, without disability progression for 10 years, after AHSCT. This kind of treatment should be considered in aggressive MS, or in disease modifying treatment nonresponsive MS patients, since appropriately timed AHSCT treatment may not only prevent disability progression but reduce

    Diarrhea, abdominal pain, and fever are common among patients undergoing hematopoietic cell transplantation (HCT), but such symptoms are also typical with foodborne infections. The burden of disease caused by foodborne infections in patients undergoing HCT is unknown. We sought to describe bacterial foodborne infection incidence after transplantation within a single-center population of HCT recipients. All HCT recipients who underwent transplantation from 2001 through 2011 at the Fred Hutchinson Cancer Research Center in Seattle, Washington were followed for 1 year after transplantation. Data were collected retrospectively using center databases, which include information from transplantation, on-site examinations, outside records, and collected laboratory data. Patients were considered to have a bacterial foodborne infection if Campylobacter jejuni/coli, Listeria monocytogenes, E. coli O157:H7, Salmonella species, Shigella species, Vibrio species, or Yersinia species were isolated in culture within 1 year after transplantation. Nonfoodborne infections with these agents and patients with pre-existing bacterial foodborne infection (within 30 days of transplantation) were excluded from analyses. A total of 12 of 4069 (.3%) patients developed a bacterial foodborne infection within 1 year after transplantation. Patients with infections had a median age at transplantation of 50.5 years (interquartile range [IQR], 35 to 57), and the majority were adults ≥18 years of age (9 of 12 [75%]), male gender (8 of 12 [67%]) and had allogeneic transplantation (8 of 12 [67%]). Infectious episodes occurred at an incidence rate of 1.0 per 100,000 patient-days (95% confidence interval, .5 to 1.7) and at a median of 50.5 days after transplantation (IQR, 26 to 58.5). The most frequent pathogen detected was C. jejuni/coli (5 of 12 [42%]) followed by Yersinia (3 of 12 [25%]), although Salmonella (2 of 12 [17%]) and Listeria (2 of 12 [17%]) showed equal frequencies; no cases of Shigella

    Full Text Available Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA biopsy sampling of enlarged lymph nodes is increasingly used to diagnose metastatic tumors, especially of the gastrointestinal tract and the lungs. Herein, we describe the diagnosis of metastatic renal cell carcinoma from a native kidney of a 54 year-old male patient, who had a 5-years history of renal transplant, by EUS-FNA of mediastinal and celiac lymph nodes. Histological and immunohistochemical findings confirmed the origin of metastatic tumor. EUS-FNA with proper cytological evaluation can be useful in the diagnosis of metastatic renal cell carcinoma in renal transplant patients

    Objective To observe the antileukemic effect in relapse patients by infusion of donor immunocompetent cells with or without granulocyte colony-stimulating factor (G-CSF) mobilization.Methods Twenty patients with leukemia in relapse after allogeneic bone marrow transplantation (allo-BMT) were treated with chemotherapy followed by donor-derived lymphocytes (DDL) without G-CSF mobilization (Group A, n=11), or donor peripheral blood progenitor cells (PBPCs) with G-CSF mobilization (Group B, n=9).Results Five patients in Group A were in hematologic relapse. After DDL infusion, 3 of 5 patients had a temporary complete remission (CR) and relapsed after 3, 7 and 10 months, respectively. One achieved partial remission and died of interstitial pneumonia; and the other one showed no response. Another 6 patients in Group A were in cytogenetic relapse or central nerve system (CNS) leukemia, and all achieved CR and remained in disease free survival (DFS) for 10 to 98 months after DDL infusion. All 9 patients in group B were in hematologic relapse. Three patients with chronic myeloid leukemia (CML) had cytogenetic and molecular remission for 16, 35 and 51 months, respectively after PBPC infusion; and 5 patients with acute lymphoid leukemia (ALL) had CR and were still in CR for 10 to 18 months except 1 patient relapsed soon. And the other one with AML showed no response to the therapy.Conclusion Donor immunocompetent cells infusion is an effective therapy for relapsed leukemia after allo-BMT, especially for the patients with early (molecular and cytogenetic) or CNS relapse. Infusion of donor PBPC mobilized by G-CSF seems to have more potentiated graft-versus-leukemia (GVL) effect than DDL infusion.

    Full Text Available Abstract Background Invasive fungal infection (IFI is associated with high morbidity and high mortality in hematopoietic stem cell transplantation (HSCT patientsThe purpose of this study was to assess the characteristics and outcomes of HSCT patients with IFIs who are undergoing MV at a single institution in Taiwan. Methods We performed an observational retrospective analysis of IFIs in HSCT patients undergoing mechanical ventilation (MV in an intensive care unit (ICU from the year 2000 to 2009. The characteristics of these HSCT patients and risk factors related to IFIs were evaluated. The status of discharge, length of ICU stay, date of death and cause of death were also recorded. Results There were 326 HSCT patients at the Linkou Chang-Gung Memorial Hospital (Taipei, Taiwan during the study period. Sixty of these patients (18% were transferred to the ICU and placed on mechanical ventilators. A total of 20 of these 60 patients (33% had IFIs. Multivariate analysis indicated that independent risk factors for IFI were admission to an ICU more than 40 days after HSCT, graft versus host disease (GVHD, and high dose corticosteroid (p p = 0.676. Conclusion There was a high incidence of IFIs in HSCT patients requiring MV in the ICU in our study cohort. The independent risk factors for IFI are ICU admission more than 40 days after HSCT, GVHD, and use of high-dose corticosteroid.

    Full Text Available The indications for transfusion of blood components support after stem cell transplantation (SCT usually do not differ form other clinical situations, but the rules for such therapy have a number of features. One of them is the possibility of inconsistence of AB0 group between donor and recipient of hematopoietic stem cells, which is not only fraught with the development of various alloimmune complications, but also fundamentally changes the standards for the selection of blood components for transfusion. A major problem after HSCT is a secondary immunodeficiency, which is important to consider for ensuring prevention of transfusion-transmitted infections (eg, CMV, as well as to carry out activities aimed for the prevention of transfusion- associated graft-versus-host disease. HSCT is a medical technology today, the effectiveness of which is often dependent on the accuracy and integrity of its implementation. So, serious attitude to various supportive therapy, including transfusions of blood components is an important component which determines the success of the treatment.

One of them is the possibility of inconsistence of AB0 group between donor and recipient of hematopoietic stem cells, which is not only fraught with the development of various alloimmune complications, but also fundamentally changes the standards for the selection of blood components for transfusion. A major problem after HSCT is a secondary immunodeficiency, which is important to consider for ensuring prevention of transfusion-transmitted infections (eg, CMV, as well as to carry out activities aimed for the prevention of transfusion- associated graft-versus-host disease. HSCT is a medical technology today, the effectiveness of which is often dependent on the accuracy and integrity of its implementation. So, serious attitude to various supportive therapy, including transfusions of blood components is an important component which determines the success of the treatment.

    We evaluated outcomes and associated prognostic factors in 233 patients undergoing allogeneic hematopoietic cell transplantation (HCT) for primary myelofibrosis (MF) using reduced-intensity conditioning (RIC). The median age at RIC HCT was 55 yr. Donors were a matched sibling donor (MSD) in 34% of RIC HCTs, an HLA well-matched unrelated donor (URD) in 45%, and a partially matched/mismatched URD in 21%. Risk stratification according to the Dynamic International Prognostic Scoring System (DIPSS) was 12% low, 49% intermediate-1, 37% intermediate-2, and 1% high. The probability of survival at 5 yr was 47% (95% confidence interval [CI], 40% to 53%). In a multivariate analysis, donor type was the sole independent factor associated with survival. Adjusted probabilities of survival at 5-yr were 56% (95% CI, 44% to 67%) for MSD, 48% (95% CI, 37% to 58%) for well-matched URD, and 34% (95% CI, 21% to 47%) for partially matched/mismatched URD (P = .002). The relative risk (RR) for NRM was 3.92 (P = .006) for well-matched URD and 9.37 (P < .0001) for partially matched/mismatched URD. Trends toward increased NRM (RR, 1.7; P = .07) and inferior survival (RR, 1.37; P = .10) were observed in DIPSS intermediate-2/high-risk patients compared with DIPSS low/intermediate-1 risk patients. Our data indicate that RIC HCT is a potentially curative option for patients with MF, and that donor type is the most important factor influencing survival in these patients.

    Recovery phase infection patterns in 55 patients who had undergone autologous blood progenitor cell transplantation (ABPCT) were evaluated retrospectively. The results were compared to those obtained in a group of 41 patients who received autologous bone marrow transplantation (ABMT). Fever related to documented or suspected infection developed in 38 of 55 patients in the ABPCT group and in 37 of 41 in the ABMT group (p 0.05). However, fewer acquired systemic fungal infections (1/55 vs. 5/41, p < 0.05) as well as fewer days of antibiotic usage were observed in the ABPCT group.

    Full Text Available BACKGROUND: Hematopoietic stem cell transplantation is a curative treatment for several haematological malignancies. However, treatment related morbidity and mortality still is a limiting factor. Cyclophosphamide is widely used in condition regimens either in combination with other chemotherapy or with total body irradiation. METHODS: We present the gene expression profile during cyclophosphamide treatment in 11 patients conditioned with cyclophosphamide for 2 days followed by total body irradiation prior to hematopoietic stem cell transplantation. 299 genes were identified as specific for cyclophosphamide treatment and were arranged into 4 clusters highly down-regulated genes, highly up-regulated genes, early up-regulated but later normalized genes and moderately up-regulated genes. RESULTS: Cyclophosphamide treatment down-regulated expression of several genes mapped to immune/autoimmune activation and graft rejection including CD3, CD28, CTLA4, MHC II, PRF1, GZMB and IL-2R, and up-regulated immune-related receptor genes, e.g. IL1R2, IL18R1, and FLT3. Moreover, a high and significant expression of ANGPTL1 and c-JUN genes was observed independent of cyclophosphamide treatment. CONCLUSION: This is the first investigation to provide significant information about alterations in gene expression following cyclophosphamide treatment that may increase our understanding of the cyclophosphamide mechanism of action and hence, in part, avoid its toxicity. Furthermore, ANGPTL1 remained highly expressed throughout the treatment and, in contrast to several other alkylating agents, cyclophosphamide did not influence c-JUN expression.

    Full Text Available AL amyloidosis is caused by clonal plasma cells that produce immunoglobulin light chains which misfold and get deposited as amyloid fibrils. Therapy directed against the plasma cell clone leads to clinical benefit. Melphalan and corticosteroids have been the mainstay of treatment for a number of years and the recent availability of other effective agents (IMiDs and proteasome inhibitors has increased treatment options. Autologous stem cell transplant (ASCT has been used in the treatment of AL amyloidosis for many years. It is associated with high rates of hematologic response and improvement in organ function. However, transplant carries considerable risks. Careful patient selection is important to minimize transplant related morbidity and mortality and ensure optimal patient outcomes. As newer more affective therapies become available the role and timing of ASCT in the overall treatment strategy of AL amyloidosis will need to be continually reassessed.

    Trisomy 8 (+8) is one of the most common cytogenetic abnormalities in adult patients with acute myeloid leukemia (AML). However, the outcome of allogeneic hematopoietic stem cell transplantation (HSCT) in adult patients with AML harboring +8 remains unclear. To evaluate, the outcome and prognostic factors in patients with AML harboring +8 as the only chromosomal abnormality or in association with other abnormalities, we retrospectively analyzed the Japanese registration data of 631 adult patients with AML harboring +8 treated with allogeneic HSCT between 1990 and 2013. In total, 388 (61%) patients were not in remission at the time of HSCT. With a median follow-up of 38.5 months, the probability of overall survival and the cumulative incidence of relapse at 3 years were 40 and 34%, respectively. In the multivariate analysis, two or more additional cytogenetic abnormalities and not being in remission at the time of HSCT were significantly associated with a higher overall mortality and relapse. Nevertheless, no significant impact on the outcome was observed in cases with one cytogenetic abnormality in addition to +8. Although more than 60% of the patients received HSCT when not in remission, allogeneic HSCT offered a curative option for adult patients with AML harboring +8.

    Full Text Available OBJECTIVE: Impaired liver regeneration is associated with a poor outcome in patients with decompensated alcoholic liver disease (ALD. We assessed whether autologous bone marrow mononuclear cell transplantation (BMMCT improved liver function in decompensated ALD. DESIGN: 58 patients (mean age 54 yrs; mean MELD score 19, all with cirrhosis, 81% with alcoholic steatohepatitis at baseline liver biopsy were randomized early after hospital admission to standard medical therapy (SMT alone (n = 30, including steroids in patients with a Maddrey's score ≥32, or combined with G-CSF injections and autologous BMMCT into the hepatic artery (n = 28. Bone marrow cells were harvested, isolated and reinfused the same day. The primary endpoint was a ≥3 points decrease in the MELD score at 3 months, corresponding to a clinically relevant improvement in liver function. Liver biopsy was repeated at week 4 to assess changes in Ki67+/CK7+ hepatic progenitor cells (HPC compartment. RESULTS: Both study groups were comparable at baseline. After 3 months, 2 and 4 patients died in the BMMCT and SMT groups, respectively. Adverse events were equally distributed between groups. Moderate alcohol relapse occurred in 31% of patients. The MELD score improved in parallel in both groups during follow-up with 18 patients (64% from the BMMCT group and 18 patients (53% from the SMT group reaching the primary endpoint (p = 0.43 (OR 1.6, CI 0.49-5.4 in an intention to treat analysis. Comparing liver biopsy at 4 weeks to baseline, steatosis improved (p<0.001, and proliferating HPC tended to decrease in both groups (-35 and -33%, respectively. CONCLUSION: Autologous BMMCT, compared to SMT is a safe procedure but did not result in an expanded HPC compartment or improved liver function. These data suggest either insufficient regenerative stimulation after BMMCT or resistance to liver regenerative drive in patients with decompensated alcoholic cirrhosis. TRIAL REGISTRATION

    Cytomegalovirus (CMV) infection is a major infectious complication after allogeneic hematopoietic cell transplantation (allo-HSCT). Recently, it was reported that CMV reactivation is associated with a decreased risk of relapse in patients with acute myeloid leukemia (AML). The aim of this study was to evaluate the impact of early CMV reactivation on the incidence of disease relapse after allo-HSCT in a large cohort of patients. The Japan Society for Hematopoietic Cell Transplantation's Transplantation-Related Complication Working Group retrospectively surveyed the database of the Transplant Registry Unified Management Program at the Japan Society for Hematopoietic Cell Transplantation. Patients with AML (n = 1836), acute lymphoblastic leukemia (ALL, n = 911), chronic myeloid leukemia (CML, n = 223), and myelodysplastic syndrome (MDS, n = 569) who underwent their first allo-HSCT from HLA-matched related or unrelated donors between 2000 and 2009 and who survived without disease relapse until day 100 after transplantation were analyzed. Patients who received umbilical cord blood transplantation were not included. Patients underwent surveillance by pp65 antigenemia from the time of engraftment, and the beginning of preemptive therapy was defined as CMV reactivation. Cox proportional hazards models were used to evaluate the risk factors of relapse, nonrelapse, and overall mortality. CMV reactivation and acute/chronic graft-versus-host disease (GVHD) were evaluated as time-dependent covariates. CMV reactivation was associated with a decreased incidence of relapse in patients with AML (20.3% versus 26.4%, P = .027), but not in patients with ALL, CML, or MDS. Among 1836 patients with AML, CMV reactivation occurred in 795 patients (43.3%) at a median of 42 days, and 436 patients (23.7%) relapsed at a median of 221 days after allo-HSCT. Acute GVHD grades II to IV developed in 630 patients (34.3%). By multivariate analysis considering competing risk factors, 3

    This work investigated the spermatogenesis in an infertility BALB/c-nu mouse model by reinfusing germline stem cells into seminiferous tubules.Donor germ cells were isolated from male FVB/NJ-GFP transgenic mice.Seminiferous tubule microiniection was applied to achieve intratubular germ cell transfer.The germ cells were injected into exposed testes of the infertility mice.We used green fluorescence and DNA analysis of donor cells from GFP transgenic mice as genetic marker.The natural mating and Southern blot methods were applied to analyze the effect of sperm cell transplantation and the sperm function after seminiferous tubule microinjecUon.The spermatogenesis was morphologically observed from the seminiferous tubules in 41/60(68.33%)of the injected recipient mice using allogeneic donor cells.In the colonized testes,matured spermatozoa were seen in the lumen of the seminiferous tubules.In this research,BALB/c-nu infertility mouse model,the recipient animal,was used to avoid immunological rejection of donor cells,and germ cell transplantation was applied to overcome infertility caused by busulfan treatment.These results demonstrate that this technique of germ cell transplantation is of great use.Germ cell transplantation could be potentially valuable to oncological patients.

    Hematopoietic cell transplantation (HCT) is an important and complex treatment modality for a variety of hematologic malignancies and some solid tumors. Although outcomes of patients who have undergone HCT and require care in intensive care units (ICUs) have improved over time, mortality rates remain high and there are significant associated costs. Lack of a team-based approach to care, especially during critical illness, is detrimental to patient autonomy and satisfaction, and to team morale, ultimately leading to poor quality of care. In this manuscript, we describe the case of a patient who had undergone HCT and was in the ICU setting, where inconsistent team interaction among the various stakeholders delivering care resulted in a lack of shared goals and poor outcomes. Team cognition is cognitive processing at the team level through interactions among team members and is reflected in dynamic communication and coordination behaviors. Although the patient received multidisciplinary care as needed in a medically complicated case, a lack of team cognition and, particularly, inconsistent communication among the dynamic teams caring for the patient, led to mixed messages being delivered with high-cost implications for the health-care system and the family. This article highlights concepts and recommendations that begin a necessary in-depth assessment of implications for clinical care and initiate a research agenda that examines the effects of team cognition on HCT teams, and, more generally, critical care of the patient with cancer.

    Treatment success in patients with acute myeloid leukaemia (AML) is heterogeneous. Cytogenetic and molecular alterations are strong prognostic factors, which have been used to individualize treatment. Here, we studied the impact of TP53 mutations on the outcome of AML patients with adverse cytogenetic risk treated with allogeneic haematopoietic stem cell transplantation (HSCT). Samples of 97 patients with AML and adverse-risk cytogenetics who had received a HSCT within three randomized trials were analysed. Complete sequencing of the TP53 coding region was performed using next generation sequencing. The median age was 51 years. Overall, TP53 mutations were found in 40 patients (41%). With a median follow up of 67 months, the three-year probabilities of overall survival (OS) and event-free survival for patients with TP53 wild type were 33% [95% confidence interval (CI), 21% to 45%] and 24% (95% CI, 13% to 35%) compared to 10% (95% CI, 0% to 19%) and 8% (95% CI, 0% to 16%) (P = 0·002 and P = 0·007) for those with mutated TP53, respectively. In multivariate analysis, the TP53-mutation status had a negative impact on OS (Hazard Ratio = 1·7; P = 0·066). Mutational analysis of TP53 might be an important additional tool to predict outcome after HSCT in patients with adverse karyotype AML.

    This study investigated specific gene expression profiles in patients with donor-specific cytotoxic-hyporesponsiveness, reflected by cytotoxic T-lymphocyte precursor frequency (CTLpf). The effect of calcineurin inhibitor (CNI) withdrawal was studied on markers for cytotoxicity (perforin, granzyme B), apoptosis (Fas,FasL), Th1 and Th2 cytokines (IL-2, IL-10), Th1 and Th2 transcription factors (T-bet, GATA 3), Th17 transcription factor and cytokine (RORγt, IL-17), and for immune regulation/activation (CD25, FOXP3). Peripheral blood samples from renal allograft recipients (n = 18) more than two yr after transplantation with stable renal function were analyzed before and four months after CNI withdrawal. Additionally, systolic and diastolic blood pressure, cholesterol, serum creatinine and proteinuria were evaluated, and no significant differences were measured before and after CNI withdrawal. However, CNIs' discontinuation influenced peripheral gene expression profiles. After CNI withdrawal, the mRNA expression of Granzyme B, Perforin, Fas, FasL, T-bet, GATA3 and CD25 were significantly lower than during CNI treatment. After CNI discontinuation, donor-specific CTLpf decreased, while FOXP3 expression discriminated between detectable and non-detectable donor-specific cytolysis reactivity; FOXP3 transcript values were highest in absence of donor-specific cytotoxicity (p < 0.01). Our study shows CNI withdrawal in stable kidney transplant recipients two yr after transplantation is safe. Moreover, discontinuation of CNIs' treatment allows FOXP3+ regulatory T-cells development, resulting in a significant decrease of anti-donor immune reactivity.

    Objective To evaluate the restoration of function after spinal cord injury (SCI) in patients of different ages who have underwent intraspinal transplantation of olfactory ensheathing cells (OECs). Methods One hundred and seventy-one SCI patients were included in this study. Of them, 139 were male and 32 were female, with age ranging from 2 to 64 years (mean, 34.9 years). In all SCI patients the lesions were injected at the time of operation with OECs. According to their ages, the patients were divided into 5 groups: ≤20 years group (n=9), 21-30 years group (n=54), 31-40 years group (n=60), 41-50 years group (n=34) and>51 years group (n=14). The spinal cord function was assessed based on the American Spinal Injury Association (ASIA) Classification System before and 2-8 weeks after OECs transplantation. One-way ANOVA and q test were used for statistical analysis, and the data were expressed as mean±SD.Results After surgery, the motor scores increased by 5.2±4.8, 8.6±8.0, 8.3±8.8, 5.7±7.3 and 8.2±7.6 in 5 age groups respectively (F=1.009, P=0.404); light touch scores increased by 13.9±8.1, 15.5±14.3, 12.0±14.4, 14.1±18.5 and 24.8±25.3 respectively (F=1.837, P=0.124); and pin prick scores increased by 11.1±7.9, 17.2±14.3, 13.2±11.8, 13.6±13.9 and 25.4±24.3 respectively (F=2.651, P=0.035). Restoration of pin prick in >51 years group was better than other age groups except 21-30 years group. Conclusion OECs transplantation can improve the neurological function of spinal cord of SCI patients regardless of their ages. Further research into the long-term outcomes of the treatment will be required.

    Respiratory syncytial virus (RSV) is a common cause of infection in immunocompromised patients and can lead to significant morbidity and mortality in pediatric hematopoietic stem cell transplantation (HSCT) patients and patients with a primary immune deficiency (PID). Palivizumab is a humanized monoclonal antibody that targets the F glycoprotein on the surface of the RSV virus, preventing RSV replication. Palivizumab was initially licensed for the prevention of RSV infections in children at high risk of severe disease. Since licensure, the American Academy of Pediatrics (AAP) has issued guidelines to help ensure appropriate use of palivizumab in pediatric patients. In the 2014 edition of the guidelines, the AAP recognizes that severe and fatal disease secondary to RSV can be seen in patients receiving chemotherapy or patients who are immunocompromised because of other conditions. However, they recognize that no large clinical trials exist to support the use of palivizumab, and efficacy and safety data in this population are limited. Despite this, the AAP recommends considering prophylaxis for children younger than 24 months who are profoundly immunocompromised during the RSV season. Because of the high cost of palivizumab, the uncertainty of its efficacy as prophylaxis in hospitalized pediatric HSCT and PID patients, and secondary to recent data from our center that suggested immunocompromised patients diagnosed with RSV did not have worse outcomes, we implemented very restrictive criteria for the use of palivizumab in the 2015 to 2016 RSV season in our pediatric HSCT population. Despite these strict criteria, there was no change in the number of patients developing RSV during this season compared with previous seasons, and there was no change in RSV course in those patients developing RSV compared with previous seasons. Restricted use also resulted in a significant dose and cost savings. Based on our experience, we recommend only administering prophylaxis

    Pneumatosis intestinalis in children is associated with a wide variety of underlying conditions and often has a benign course. The CT features of this condition have not been systematically investigated. Defining benign pneumatosis intestinalis as pneumatosis intestinalis that resolved with medical management alone, we sought to: (1) determine whether the incidence of benign pneumatosis intestinalis had increased at our pediatric cancer hospital; (2) characterize CT features of benign pneumatosis intestinalis; and (3) determine the relationship between imaging features and clinical course of benign pneumatosis intestinalis in this cohort. Radiology reports from November 1994 to December 2006 were searched for ''pneumatosis intestinalis,'' ''free intraperitoneal air,'' and ''portal venous air or gas.'' Corresponding imaging was reviewed by two radiologists who confirmed pneumatosis intestinalis and recorded the presence of extraluminal free air, degree of intramural gaseous distension, number of involved bowel segments, and time to pneumatosis resolution. The search revealed 12 boys and 4 girls with pneumatosis intestinalis; 11 were hematopoietic stem cell transplant recipients. The annual incidences of benign pneumatosis have not changed at our institution. Increases in intramural distension marginally correlated with the number of bowel segments involved (P=0.08). Three patients had free air and longer times to resolution of pneumatosis (P=0.03). Male children may be at increased risk of benign pneumatosis intestinalis. The incidence of benign pneumatosis at our institution is proportional to the number of hematopoietic stem cell transplants. The degree of intramural distension may correlate with the number of bowel segments involved. Patients with free air have a longer time to resolution of benign pneumatosis. (orig.)

    There are limited clinical investigations identifying the percentage of T helper 1 (Th1) and T regulatory (Treg) cells in stable as well as rejected kidney allografts, a concept which needs to be more studied. The aim of our study was to compare the percentage of CD4+ IFN-γ+ cells, the number of IFN-γ secreting cells and the amount of FoxP3 expression in patients with or without stable graft function, to determine the roles of these immunological factors in stable and rejected renal allografts. In this prospective study, 3 months after transplantation 30 patients who received renal transplants from unrelated living donors were enrolled and divided into two groups, 20 patients with stable graft function and 10 patients with biopsy proven acute rejection. The percentage of Th1 CD4+ IFN-γ+ cells was determined on PBMC by flow cytometry and the number of IFN-γ secreting cells by ELISPOT method. Furthermore, FoxP3 expression of PBMCs was measured by Real Time PCR method. The results of these assessments in both groups were statistically analyzed by SPSS 14.0. Our results showed that the percentage of Th1 CD4+ IFN-γ+ cells and the number of IFN-γ secreting cells were significantly higher in the patients with acute rejection in comparison to the stable graft function group (p<0.001). In addition, the level of FoxP3 gene expression was higher in the group with stable graft compared to the acute rejection group. The higher percentage of CD4+ IFN-γ+Th1 subset and number of IFN-γ secreting cells and also the lower expression of Foxp3 could prone the patients to acute rejection episode post transplantation. By these preliminary data, it is suggested that monitoring of Th1 cells post transplantation, as an immunologic marker could predict the possibility of rejection episodes.

    Natural killer (NK) cells play a central role in the innate immune system. In allogeneic stem cell transplantation (alloSCT), alloreactive NK cells derived by the graft are discussed to mediate the elimination of leukemic cells and dendritic cells in the patient and thereby to reduce the risk for leukemic relapses and graft-versus-host reactions. The alloreactivity of NK cells is determined by various receptors including the activating CD94/NKG2C and the inhibitory CD94/NKG2A receptors, which both recognize the non-classical human leukocyte antigen E (HLA-E). Here we analyze the contribution of these receptors to NK cell alloreactivity in 26 patients over the course of the first year after alloSCT due to acute myeloid leukemia, myelodysplastic syndrome and T cell Non-Hodgkin-Lymphoma. Our results show that NK cells expressing the activating CD94/NKG2C receptor are significantly reduced in patients after alloSCT with severe acute and chronic graft-versus-host disease (GvHD). Moreover, the ratio of CD94/NKG2C to CD94/NKG2A was reduced in patients with severe acute and chronic GvHD after receiving an HLA-mismatched graft. Collectively, these results provide evidence for the first time that CD94/NKG2C is involved in GvHD prevention. PMID:27801784

    Late-onset hemorrhagic cystitis (LHC) after hematopoietic stem cell transplantation (HSCT) is mainly caused by viral infections. We retrospectively analyzed the records of 141 Japanese adult patients who underwent a first allogeneic HSCT from 1995 to 2002. In all, 19 patients developed LHC a median of 51 days after HSCT. Adenovirus (AdV) was detected in the urine of 10 LHC patients, of whom eight had AdV type 11. Five of the six available serum samples from these patients were also positive for AdV type 11, but the detection of AdV in serum was not associated with a worse outcome. Male sex and the development of grade II-IV acute graft-versus-host disease were identified as independent significant risk factors for LHC. Male predominance was detected in LHC after HSCT, as has been previously shown in children with AdV-induced acute HC. The detection of AdV DNA in serum did not predict a poor outcome.

    Elevated serum ferritin contributes to treatment-related morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). The multicenter DE02 trial assessed the safety, efficacy and impact of deferasirox on iron homeostasis after allogeneic HSCT. Deferasirox was administered at a starting dose of 10 mg/kg per day to 76 recipients of allogeneic HSCT, with subsequent dose adjustments based on efficacy and safety. Deferasirox was initiated at a median of 168 days after HSCT, with 84% of patients still on immunosuppression. Baseline serum ferritin declined from 2045 to 957 ng/mL. Deferasirox induced a negative iron balance in 84% of patients. Hemoglobin increased in the first 3 months, and trough serum cyclosporine levels were stable. Median exposure was 330 days, with a median compliance rate of >80%. The most common investigator-reported drug-related adverse events (AEs) were increased blood creatinine (26.5%), nausea (9.0%) and abdominal discomfort (8.3%). Fifty-four (71.1%) patients experienced drug-related AEs, which occasionally resulted in discontinuation (gastrointestinal (n=6), skin (n=3), elevated transaminases (n=1) and creatinine (n=1)). The incidence of AEs appeared to be dose related, with 7.5 mg/kg per day being the best-tolerated dose. Low-dose deferasirox is an effective chelation therapy after allogeneic HSCT, with a manageable safety profile, even in patients receiving cyclosporine.

    SOT may be indicated for a select group of pediatric patients who experience permanent organ failure following HSCT. However, there is limited information available about outcomes. We identified eight children at our center who received an SOT following an HSCT. Patients were six months to 18 yr at HSCT. Diseases for which children underwent HSCT included thalassemia, Wiskott-Aldrich syndrome, Shwachman-Diamond/bone marrow failure, sickle cell disease (SCD), erythropoietic porphyria (EP), ALL, chronic granulomatous disease, and neuroblastoma. Time from HSCT to SOT was 13 days to seven yr (median, 27 months. Lung SOT was performed for two patients with BO, kidney transplants for three patients, and liver transplants for three patients (VOD, chronic GVHD). Seven patients are alive with functioning allografts 6-180 months from SOT. Advances in organ procurement, operative technique, immunosuppressant therapy, and infection control may allow SOT for a select group of patients post-HSCT. However, scarcity of donor organs available in a timely fashion continues to be a limiting factor. Children who have undergone HSCT and develop single organ failure should be considered for an SOT if there is a high likelihood of cure of the primary disease.

    We examined retrospectively 44 patients with refractory acute leukemia (acute myeloid leukemia (AML)/acute lymphoblastic leukemia=25/19) who underwent allogeneic transplantation at our center between 11/1990 and 04/2004. The median leukemic blasts was 25% and age 28 years (range, 3-56). Twenty-one patients had untreated relapse, 13 failed reinduction, eight in partial remission and two aplastic. Conditioning was myeloablative using cyclophosphamide, busulfan, total-body irradiation and etoposide (Bu/Cy/VP, n=22; TBI/Cy/VP, n=17; others, n=5) followed by marrow or peripheral blood transplant (n=23/21) from unrelated or related donors (n=28/16). All patients had graft-versus-host disease (GVHD) prophylaxis with cyclosporin and methotrexate. One patient experienced late graft failure. Severe acute-GVHD and chronic-GVHD appeared in eight and 14 patients, respectively. Thirteen patients (30%) remain alive after a median of 25.3 months (range, 2.4-134.1); with 31 deaths, mostly from relapse (n=15) and infections (n=12). Overall survival (OS) and progression-free survival (PFS) at 5 years was 28 and 26%, respectively. OS and PFS were significantly better with blasts < or =20% and time to transplant < or =1 year while transplant-related mortality was less with the use of TBI. We conclude that patients with refractory leukemia can benefit from allogeneic BMT, especially with < or =20% marrow blast.

    In addition to prescribed conventional medicines, many allogeneic hematopoietic stem cell transplant (HSCT) survivors also use complementary and alternative medical therapies (CAM), however, the frequency and types of CAMs used by allogeneic HSCT survivors remain unclear. Study participants were adults who had undergone an allogeneic HSCT between 1st January 2000 and 31st December 2012. Participants completed a 402-item questionnaire regarding the use of CAM, medical complications, specialist referrals, medications and therapies, infections, vaccinations, cancer screening, lifestyle, and occupational issues and relationship status following stem cell transplantation. A total of 1475 allogeneic HSCT were performed in the study period. Of the 669 recipients known to be alive at study sampling, 583 were contactable and were sent study packs. Of 432 participants who returned the completed survey (66% of total eligible, 76% of those contacted), 239 (54.1%) HSCT survivors used at least one form of CAM. These included dietary modification (13.6%), vitamin therapy (30%), spiritual or mind-body therapy (17.2%), herbal supplements (13.5%), manipulative and body-based therapies (26%), Chinese medicine (3.5%), reiki (3%), and homeopathy (3%). These results definitively demonstrate that a large proportion of HSCT survivors are using one or more form of CAM therapy. Given the potential benefits demonstrated by small studies of specific CAM therapies in this patient group, as well as clearly documented therapies with no benefit or even toxicity, this result shows there is a large unmet need for additional studies to ascertain efficacy and safety of CAM therapies in this growing population.

    Allogeneic hematopoietic cell transplantation (HCT) offers curative therapy for many patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). However, post-HCT relapse remains a major problem, particularly in patients with high-risk cytogenetics. In this prospective phase II trial we assessed the efficacy and toxicity of treosulfan, fludarabine and 2 Gy total body irradiation (TBI) as conditioning for allogeneic HCT in patients with MDS or AML. Ninety-six patients with MDS (n=36; 15 RMCD; 10 RAEB-1; 10 RAEB-2; 1 CMML-1) or AML (n=60; 35 CR1; 18 CR2; 3 advanced CR; 4 refractory relapse) were enrolled; median age was 51 (range: 1–60) years. Twelve patients had undergone a prior HCT with high intensity conditioning. Patients received intravenous (IV) treosulfan, 14 g/m2/day on days −6 to −4, IV fludarabine, 30 mg/m2/day on days −6 to −2, and 2 Gy TBI on day 0, followed by infusion of hematopoietic cells from related (n=27) or unrelated (n=69) donors. Graft-vs.-host disease prophylaxis consisted of tacrolimus and methotrexate. With a median follow-up of 30 months, the 2-year overall survival (OS), relapse incidence and non-relapse mortality were 73%, 27% and 8%, respectively. The incidences of grades II–IV (III–IV) acute and chronic graft-versus-host disease were 59% (10%) and 47%, respectively. Two-year OS was not significantly different between MDS patients with poor risk and good/intermediate risk cytogenetics (69% and 85%, respectively), or between AML patients with unfavorable and favorable/intermediate risk cytogenetics (64% and 76%, respectively). In AML patients, minimal residual disease (MRD; n=10) at the time of HCT predicted higher relapse incidence (70% vs. 18%) and lower OS (41% vs. 79%) at 2 years, when compared to patients without MRD. In conclusion, treosulfan, fludarabine and low-dose TBI provided effective conditioning for allogeneic HCT in patients with MDS or AML, and resulted in low relapse incidence, regardless

    Full Text Available Allogeneic stem cell transplantation (allo-HSCT is one of the curative treatments for hematologic malignancies, but is hampered by severe complications, such as acute or chronic graft-versus-host-disease (aGvHD; cGvHD and infections. CD34-selcetion of stem cells reduces the risk of aGvHD, but also leads to increased infectious complications and relapse. Thus, we studied the efficacy, safety and feasibility of transfer of gene modified donor T-cells shortly after allo-HSCT in two clinical trials between 2002 and 2007 and here we compare the results to unmodified donor leukocyte transfusion (DLI. The aim of these trials was to provide patients with the protection of T-cells after T-cell-depleted allo-HSCT in the matched or mismatched donor setting with an option to delete transduced T-cells, if severe aGvHD occurred within the trial period. Donor-T-cells were transduced with the replication-deficient retrovirus SFCMM-3, expressing HSV-Tk and the truncated LNGFR for selection of transduced cells. Transduced cells were transfused either after day +60 (matched donors or on day +42 (haploidentical donors.Nine patients were included in the first trial (MHH; 2002 until 2007 2 were included in TK007 (2005-2009 and 6 serve as a control group for outcome after haploidentical transplantation without HSV-TK-transduced DLI. Three patients developed acute GvHD, two had grade I of the skin, one had aGvHD on day +131 (post-HSCT; +89 post-HSV-Tk DLI grade II, which was successfully controlled by ganciclovir (GCV. Donor chimerism was stabilized after transfusion of the transduced cells in all patients treated. Functionality of HSV-Tk gene expressing T-cells was shown by loss of bcr-abl gene expression as well as by control of cytomegalovirus-reactivation. To date, 6patients have relapsed and died, 2 after a second HSCT without T-cell depletion or administration of unmodified T-cells. Eleven patients (7 post-HSV-Tk DLI are alive and well to date.

    Full Text Available In the last decades, the global epidemiological impact of invasive candidiasis (IC in patients with hematologic malignancies (HM and in hematopoietic stem cell transplant (HSCT recipients has decreased and the incidence of invasive aspergillosis  exceeded that of Candida infections. The use of prevention strategies, first of all antifungal prophylaxis with triazoles,  contributed to the reduction of IC in these populations as demonstrated by several  epidemiological studies. However, relatively little is known about the current epidemiological patterns of IC in HM and HSCT populations, because recent epidemiological data almost exclusively derive from retrospective experiences and few prospective data are available. Several prospective, controlled studies in the prophylaxis of invasive fungal diseases have been conducted in both the HM and HSCT setting. On the contrary, most of the prospective controlled trials that demonstrated the efficacy of the antifungal drugs echinocandins and voriconazole in the treatment of candidemia and invasive candidiasis mainly involved  patients with underlying conditions other than HM or  HSCT.  For these reasons, international guidelines provided specific indications for the prophylaxis strategies in HM and HSCT patients, whereas the  recommendations on therapy of documented Candida infections are based on the results observed in the general population and should be considered with caution.

    To analyze the outcome of solid organ transplantation (SOT) in patients who had undergone allogeneic hematopoietic stem cell transplantation (HSCT), a questionnaire survey was carried out within 107 European Group of Blood and Marrow Transplantation centers. This study covered HSCT between 1984...... and 2007 in Europe. Forty-five SOT in 40 patients were reported. Fifteen liver, 15 renal, 13 lung, 1 heart and 1 skin transplantations were performed in 28 centers. Overall survival (OS) of patients after SOT was 78% at 5 years (95% confidence interval [CI], 64% to 92%). OS at 5 years was 100% for renal......, 71% (95% CI, 46% to 96%) for liver and 63% (95% CI, 23% to 100%) for lung transplant recipients. The 2-year-incidence of SOT failure was 20% (95% CI, 4% to 36%) in patients with graft-versus-host disease (GvHD) and 7% (95% CI, 0% to 21%) in patients without GvHD before SOT.

    Full Text Available Marwan Raymond Atallah, Sotiria Palioura, Victor L Perez, Guillermo Amescua Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, Miami, FL, USA Abstract: Regeneration of the corneal surface after an epithelial insult involves division, migration, and maturation of a specialized group of stem cells located in the limbus. Several insults, both intrinsic and extrinsic, can precipitate destruction of the delicate microenvironment of these cells, resulting in limbal stem cell deficiency (LSCD. In such cases, reepithelialization fails and conjunctival epithelium extends across the limbus, leading to vascularization, persistent epithelial defects, and chronic inflammation. In partial LSCD, conjunctival epitheliectomy, coupled with amniotic membrane transplantation, could be sufficient to restore a healthy surface. In more severe cases and in total LSCD, stem cell transplantation is currently the best curative option. Before any attempts are considered to perform a limbal stem cell transplantation procedure, the ocular surface must be optimized by controlling causative factors and comorbid conditions. These factors include adequate eyelid function or exposure, control of the ocular surface inflammatory status, and a well-lubricated ocular surface. In cases of unilateral LSCD, stem cells can be obtained from the contralateral eye. Newer techniques aim at expanding cells in vitro or in vivo in order to decrease the need for large limbal resection that may jeopardize the “healthy” eye. Patients with bilateral disease can be treated using allogeneic tissue in combination with systemic immunosuppressive therapy. Another emerging option for this subset of patients is the use of noncorneal cells such as mucosal grafts. Finally, the use of keratoprosthesis is reserved for patients who are not candidates for any of the aforementioned options, wherein the choice of the type of keratoprosthesis depends on

    The aim of this exploratory study was to investigate the isolation and expansion of keratinocytes and fibroblasts from donors with certain medical histories. Biopsies were taken from donors (N=32) falling into one or more of the following categories: a history of heavy smoking and/or alcohol abuse, drug abuse, diabetes mellitus or steroid treatment. Cells from donors who did not fall into any of the above-mentioned categories were used as controls. Proliferation and growth behaviour of cells were analyzed by measurement of passage duration, absorbance (MTT-assay) and light microscopy. Donors with a specific medical history required larger biopsy areas than the control group for isolating a sufficient number of fibroblasts and keratinocytes. Times to confluence were significantly prolonged and absorbances (MTT) were significantly reduced in several donor groups when compared to control cultures. Biopsies from donors with steroid treatment, drug abuse and combined nicotine and alcohol abuse could not be established beyond passage 0 degrees or 1 degree, respectively. We conclude that isolation and expansion of skin cells from donors with certain medical histories may require larger biopsies, prolonged expansion times or may even result in failure. These findings may therefore be of clinical importance in the field of autologous skin cell transplantation.

    Umbilical cord blood transplantation has been successfully employed for treatment of many immune and hematologic disorders. The aim of this study was to evaluate the quality of immune reconstitution after umbilical cord blood transplantation in 6 leukemia children. T-cell receptor Vbeta third complementary region spectratyping was used for monitoring the contribution of the thymic pathway in patients' immune reconstitution. Absolute numbers of lymphocyte subsets (T, B, and natural killer), and lymphoproliferative in vitro response to mitogens, recovered within 12 months after transplantation. Furthermore, an overall diversification of T-cell receptor complexity in the repopulating T cells, with a polyclonal Gaussian profiles in most (74%) of total families was observed. Noteworthy, we showed a wider and more rapid reconstitution of T-cell receptor CD4+ T cell families compared with T-cell receptor CD8+ T ones still exhibiting some perturbations at 24 months. These data show that umbilical cord blood transplantation allows immune reconstitution already within 12 months with generation of newly diversified CD4+ T lymphocyte subsets.

    Full Text Available Older adults with Acute Myeloid Leukaemia (AML, when compared to younger patients with the same disease, have a poor prognosis and represent a discrete population in terms of disease biology, treatment-related complications, and overall outcome. As a result, older patients require distinctive management approaches. For 85%-95% of older AML patients, any therapy ultimately will be purely palliative. No randomized trial has ever demonstrated that any amount of post-remission therapy in older AML patients provides better outcomes than no post-remission therapy. The only studies demonstrating that long-term Disease Free Survival (DFS is possible in older AML patients have included remission induction and post-remission therapy. For these reasons alternative post-remission strategies, including autologous or allogeneic transplantation have been explored also in people over sixty considered fit for aggressive therapy. Up to now the data available from clinical trials suggest that the stem cell transplant procedure is promising, and can lead to long-term survival, but it is feasible only in a minority of fit elderly patients. The main limits of Autologous Stem Cell Transplantation (ASCT are represented by the low percentage of patients able to mobilize a sufficient amount of stem cells and by the still high relapse incidence after ASCT, especially in those with poor prognostic factors; for these patients the allogeneic transplant procedure, by using non myeloablative conditioning regimens, could offer a better chance of cure, thanks to the Graft versus Leukemia (GVL effect, but there are no prospective trials showing the superiority of any transplant approach over conventional treatment in this subset of patients.Pacientes idosos com leucemia mielóide aguda (LMA, quando comparados com pacientes jovens com a mesma doença, apresentam prognóstico pobre e representam uma população particular em termos biológicos, complicações relacionadas ao

    The aim of the study was investigate the long-term results of autologous bone marrow CD 133+ cell transplantation in patients with primary ST-Elevation Myocardial Infarction (STEMI). Methods and results: From 2006 to 2007, 26 patients with primary STEMI were included in an open randomized study. Patients were randomized to two groups: 1st - included patients underwent PCI and transplantation of autologous bone marrow CD 133+ cell (n = 10); 2nd - patients with only PCI (n = 16). Follow-up study was performed 7.70±0.42 years after STEMI and consisted in physical examination, 6-min walking test, Echo exam. Total and cardiovascular mortality in group 1 was lower (20% (n = 2) vs. 44% (n = 7), p = 0.1 and 22% (n = 2) vs. 25% (n = 4), (p=0.53), respectively). Analysis of cardiac volumetric parameters shows significant differences between groups: EDV of 100.7 ± 50.2 mL vs. 144.40±42.7 mL, ESV of 56.3 ± 37.8 mL vs. 89.7 ± 38.7 mL in 1st and 2nd groups, respectively. Data of the study showed positive effects of autologous bone marrow CD 133+ cell transplantation on the long-term survival of patients and structural status of the heart.

    In a previous prospective study on 62 patients who underwent an HLA-matched allogeneic stem cell transplantation, we have observed that proportion of donor-derived CCR7(+)/CD4(+) T cells in the graft provided a predictive indicator of acute GVHD without interfering on chronic GVHD and relapse rate. Here we present our results on a confirmatory cohort of 137 consecutive patients. Indeed patients who received more than 76% of CCR7(+)/CD4(+) T cells in the graft developed more often acute GVHD be it of low or high grade than those who did not. Determination of the CCR7(+)/CCR7(neg) ratio of CD4(+) T cells in the graft provides a predictive indicator of acute GVHD and could help to define strategies of partial selective T cell depleted transplantation.

    Allogeneic hematopoietic stem cell transplantation (HSCT) is a procedure with a high risk of treatment related mortality. The primary aim of the present study was to examine associations between markers of gastrointestinal toxicity, markers of systemic inflammation, and plasma levels of microRNA (miRNA) -155 and -146a during the first month after HSCT. The secondary aim was to characterize the impact of the toxic-inflammatory response on the function of circulating leukocytes during immune recovery. Thirty HSCT patients were included. Gastrointestinal injury was monitored by toxicity scores, lactulose-mannitol test and plasma citrulline, as a measure of the enterocyte population. Nadir of citrulline and maximum of oral toxicity scores, intestinal permeability, CRP and plasma levels of IL-6 and IL-10 was seen at day +7 post-HSCT. miRNA-155 and mi-RNA-146a showed an inverse relation with significantly elevated miRNA-155 and decreased miRNA-146a levels, from day 0 to day +28 compared with pre-conditioning levels. Citrulline levels below the median at day +7 were associated with higher spontaneous production of IL-6 and TNF-α as well as higher in vitro stimulated production of IL-17A at day +21. This study is the first to demonstrate that toxic responses to chemotherapy are accompanied by differential regulation of miRNAs with opposing effects on immune regulation. We find that a proinflammatory miRNA profile is sustained during the first three weeks after the transplantation, indicating that these miRNAs may play a role in the regulation of the inflammatory environment during immune reconstitution after HSCT.

    Purpose: We have demonstrated that toxicities are acceptable with total marrow irradiation (TMI) at 16 Gy without chemotherapy or TMI at 12 Gy and the reduced intensity regimen of fludarabine/melphalan in patients undergoing hematopoietic cell transplantation (HCT). This article reports results of a study of TMI combined with higher intensity chemotherapy regimens in 2 phase I trials in patients with advanced acute myelogenous leukemia or acute lymphoblastic leukemia (AML/ALL) who would do poorly on standard intent-to-cure HCT regimens. Methods and Materials: Trial 1 consisted of TMI on Days -10 to -6, etoposide (VP16) on Day -5 (60 mg/kg), and cyclophosphamide (CY) on Day -3 (100 mg/kg). TMI dose was 12 (n=3 patients), 13.5 (n=3 patients), and 15 (n=6 patients) Gy at 1.5 Gy twice daily. Trial 2 consisted of busulfan (BU) on Days -12 to -8 (800 {mu}M min), TMI on Days -8 to -4, and VP16 on Day -3 (30 mg/kg). TMI dose was 12 (n=18) and 13.5 (n=2) Gy at 1.5 Gy twice daily. Results: Trial 1 had 12 patients with a median age of 33 years. Six patients had induction failures (IF), and 6 had first relapses (1RL), 9 with leukemia blast involvement of bone marrow ranging from 10%-98%, 5 with circulating blasts (24%-85%), and 2 with chloromas. No dose-limiting toxicities were observed. Eleven patients achieved complete remission at Day 30. With a median follow-up of 14.75 months, 5 patients remained in complete remission from 13.5-37.7 months. Trial 2 had 20 patients with a median age of 41 years. Thirteen patients had IF, and 5 had 1RL, 2 in second relapse, 19 with marrow blasts (3%-100%) and 13 with peripheral blasts (6%-63%). Grade 4 dose-limiting toxicities were seen at 13.5 Gy (stomatitis and hepatotoxicity). Stomatitis was the most frequent toxicity in both trials. Conclusions: TMI dose escalation to 15 Gy is possible when combined with CY/VP16 and is associated with acceptable toxicities and encouraging outcomes. TMI dose escalation is not possible with BU/VP16 due to

    Delayed platelet recovery is a significant complication after both autologous and allogeneic hematopoietic stem cell transplantation (HSCT). A multicenter, phase I dose-escalation study of recombinant human thrombopoietin (rhTPO) was conducted to assess its safety and to obtain preliminary data on its efficacy in patients with persistent severe thrombocytopenia (35 days after HSCT. Thirty-eight patients, 37 of whom were evaluable, were enrolled in the study from April 1996 through January 1997. rhTPO was administered at doses of 0.6, 1.2, and 2.4 microg/kg as a single dose (group A) or in multiple doses every 3 days for a total of 5 doses (group B). No significant adverse effects were observed. Ten patients had recovery of platelet counts during the 28-day study period; 3 of these 10 had an increase in marrow megakaryocyte content 7 days after completing treatment with rhTPO. When all baseline marrows were compared with samples after rhTPO treatment, there was no difference in marrow megakaryocyte content (P = 0.49). This study design could not answer the question of whether the recoveries of platelet counts observed in some patients were spontaneous or influenced by rhTPO treatment; nonetheless, the authors found no correlation between the dose of rhTPO and the recovery of platelet counts. Increases in serum TPO levels were dose-dependent and remained significantly elevated for up to 72 hours after treatment. To evaluate response, further studies of treatment strategies with rhTPO in patients with delayed platelet recovery are required.

    Pneumocystis jirovecii prophylaxis is standard in allogeneic stem cell transplantation (alloSCT), sometimes with pentamidine at a low dose inhaled monthly. Human metabolism of pentamidine depends on cytochrome P450 2C19 (CYP2C19). The frequency of mutant CYP2C19 forms with decreased function (from 2% of Caucasians to 30% of Asians and 79% of certain Polynesians), together with common use of CYP2C19 inhibitors in the alloSCT process, creates risk for impaired pentamidine clearance resulting in toxicity ordinarily expected only with high doses given for active infection. We examined the charts of 32 consecutive pentamidine-prophylaxed alloSCT patients at our center. We assessed hospital charges for the management of toxicities unexplained at the time but likely attributable, in retrospect, to pentamidine. Twenty-eight percent experienced significant toxicities (incurring added charges of at least US$5000). Thirteen percent suffered major toxicity (incurring added charges of at least US$25, 000; median added charge $351, 701) and shorter survival (326 vs. 622 d for all pentamidine recipients), including 6% who died of pentamidine toxicities [one proven postmortem to have a (non-functional) homozygous CYP2C19*2 mutation]. Charges for care attributable to pentamidine toxicity exceeded what preemptive genotyping would have cost by 73-fold. These findings encourage routine use of preemptive CYP2C19 genotyping in alloSCT patients considered for pentamidine.

    Objective: To determine the sensitivity and significance of B-cell chimerism for the detection of early engraftment, transplant rejection, and disease relapse. Methods: The dynamic monitoring of lineage-specific cell subtypes (B, T, and NK cells) was made in 20 B-cell acute lympho-blastic leukemia (B-ALL) patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT). In the early period after allo-HSCT, the latest establishment of B-cell complete chimerism (CC) was observed in a majority of patients. Results: The percentage of donor cells of B-cell lineage was lower than the percent of T-cell lineage in most of the mixed chimerism (MC) patients. During graft rejection, the frequency of patients with decreasing MC of B-, T-and NK-cell lineage were 5/5, 2/5, and 2/5. When disease relapsed, five patients showed a faster decrease of the donor percent of B-cells than of T-or NK-cells. Only one patient displayed a more rapid decrease in NK-cells than in T-or B-cells. Conclusion: Monitoring of B-cell chimerism after HSCT seems to be valuable for insuring complete engraftment, anticipating graft rejection, and relapse in B-ALL patients.

    Prior studies report that 9-27% of persons receiving a hematopoietic cell transplant develop arrhythmias, but the effect on outcomes is largely unknown. We reviewed data from 1177 consecutive patients ⩾40 years old receiving a hematopoietic cell transplant at one center during 1999-2009. Transplant indication was predominately leukemia, lymphoma and multiple myeloma. Overall, 104 patients were found to have clinically significant arrhythmia: 43 before and 61 after transplant. Post-transplant arrhythmias were most frequently atrial fibrillation (N=30), atrial flutter (N=7) and supraventricular tachycardia (N=11). Subjects with an arrhythmia post transplant were more likely to have longer median hospital stays (32 days vs 23, P=transplant (41% vs 15%; Ptransplant, diagnosis, history of pretransplant arrhythmia, and transplant-related variables, post-transplant arrhythmia was associated with a greater risk for death within a year of transplant (odds ratio 3.5, 95% confidence interval: 2.1, 5.9; Ptransplants are associated with significant morbidity and mortality. A prospective study of arrhythmia in the transplant setting is warranted.

    Improved outcomes in liver transplant recipients reflect advances in surgical technique, post-operative care, immunosuppression as well as better selection of potential candidates. The pre-transplant evaluation is a multidisciplinary process intended to recognize and treat important comorbid conditions that may impair outcomes during the peri- and post-transplant periods. Important psychosocial issues should also be ascertained and tackled early during the pre-transplant evaluation with an overarching intention to improve the success of liver transplantation.

    Full Text Available Background: Human tear film plays an important role in protecting the ocular surface against vari­ous pathogens. Dry eye, the major ocular complication of peripheral blood stem cell trans­plantation (PBSCT, may predispose bacterial colonization to the conjunctiva, and increase the risk of infectious keratitis. The aim of this study is to investigate the con­junctival bacterial flora in patients receiving PBSCT and to stratify the severity of dry eye for comparison. Methods: This cross-sectional study encompassed patients who received PBSCT from 2002 to 2008 in our hospital. At least 1 year after PBSCT, patients were re-evaluated for ocu­lar surface status, and bacterial culture of the conjunctival sac was performed. The eyes of patients were divided into three groups in accordance to the result of the Schirmer Ia test. In the control group, we enrolled dry-eye patients with underlying dis­ease other than hematopoietic stem cell transplantation of which the age range was simi­lar to the study group. Results: Thirty-six patients with 72 eyes were included in our study. The first group (n=36 was defined as having Schirmer Ia test result of 0-5 mm, and the culture of conjuncti­val sac were positive in 8 eyes (22%. The second group (n=20 was defined as having Schirmer Ia result between 6 and 9 mm, and 4 of which were positive for bacterial cul­ture (20%. In the third group (n=16 with Schirmer Ia result of ≧10mm, flora in pa­tients receiving PBSCT were coagulase-negative Staphylococci, Staphylococcus au­reus and Corynebacterium sp. The bacterial colonization rate in the post-PBSCT group was not higher than the control group (22.2% vs. 30.8%, and coagulase-nega­tive Staphylococci was the most common flora in the control group. Conclusion: Despite not having statistical significance, there seems to be a positive correlation be­tween the colonization rate and the severity of dry eye.

    Objective: The purpose of this article is to describe and illustrate the acute and follow-up imaging features, clinical constellation and outcome of patients with thoracic air-leakage syndrome following allogeneic hematopoietic stem cell transplantation (allo-HCT). Methods: Patients with evidence of thoracic air-leakage, i.e. spontaneous pneumomediastinum, spontaneous pneumothorax or interstitial emphysema after allo-HCT were retrospectively identified by a chart review. Acute and follow-up morphology, duration and patient outcome were analyzed on CT (HRCT or MSCT with HR-reconstructions). Correlation was made with histological results of transbronchial biopsy. Results: The 6 patients included (3 male and 3 female, 14-64 years old) with thoracic air-leakage after allo-HCT all had histologically proven bronchiolitis obliterans (BO) or bronchiolitis obliterans organizing pneumonia (BOOP). Thoracic air-leakage consisted of spontaneous pneumomediastinum associated with active invasive pulmonary aspergillosis (IPA) in 4/6 and spontaneous pneumothorax or interstitial emphysema each in 1/6 patients. Duration of thoracic air-leakage was 7-135 days. Of the patients with spontaneous pneumomediastinum, 3/4 died of IPA. One patient survived until complete regression of spontaneous pneumomediastinum. One patient died 7 days after spontaneous pneumothorax and one survived developing chronic interstitial emphysema. Conclusion: In all cases, thoracic air-leakage was associated to BO or BOOP. In the majority of cases with additional IPA, thoracic air-leakage is more indicative for severity of pulmonary disease than a life-threatening entity itself.

    Few studies have evaluated the risk factors for hepatic sinusoidal obstructive syndrome (SOS) in patients with malignant lymphoma receiving autologous stem cell transplantation (ASCT). We retrospectively analyzed 132 malignant lymphoma patients who underwent ASCT. Intravenous busulfan-based conditioning regimens were used in 108 (81.8%) patients. The combination of heparin and ursodeoxycholic acid was used for prophylaxis of SOS. Hepatic SOS was developed in 10 (7.6%) patients at a median of 30 days post-ASCT. In nine (90.0%) patients, SOS was diagnosed after 20 days post-ASCT. Two patients developed severe SOS and eventually died from multiple organ failure. In multivariate analysis, the use of the busulfan-thiotepa conditioning regimen (p = 0.003) and a high pre-transplant serum ferritin level (≥ 950 ng/mL) (p = 0.003) were risk factors for hepatic SOS. The evaluation of pre-transplant serum ferritin may be helpful in determining the most appropriate conditioning regimen with a lower risk of SOS.

    Background Allogeneic peripheral blood stem cell transplantation from unrelated donors (UR-PBSCT) is an alternative treatment for many hematologic diseases due to lack of human leukocyte antigen (HLA)-identical sibling donors.This study aimed to evaluate the impact of the degree of the HLA match on the clinical efficacy of UR-PBSCT.Methods Patients who underwent UR-PBSCT from September 2003 to September 2012 were retrospectively investigated.They were divided into three groups according to high-resolution molecular typing.SPSS version 17.0 was used to analysis and compare the statistics of engraftment,incidence of GVHD,other complications and survival among the groups.Results One hundred and eleven patients received UR-PBSCT,60 of them with an HLA matched donor (10/10),36 of them with a one locus mismatched donor (9/10),and 15 of them with a two loci mismatched donor (8/10).Similar basic characteristics were found in the three groups.No differences were found in engraftment of myeloid cells or platelets in the three groups (P>0.05).Two-year cumulative incidence of relapse,overall survival (OS) and disease-free survival (DFS) among those three groups were similar (P>0.05).The cumulative incidence of 100-day Ⅲ-Ⅳ aGVHD in the HLA matched group and the one HLA locus mismatched group were significantly lower than that in the two HLA loci mismatched group (3.3%,8.6%,and 26.7%,P=0.009).The occurrence rate of new pulmonary infections in the HLA matched group was lower than in the two HLA mismatched groups (26.67%,52.78%,and 41.18%,P=0.035).The cumulative incidence of 100-day and 2-year transplantation related mortality (TRM) in two HLA loci mismatched group was higher than in the HLA matched group and in the one HLA locus mismatched group,(8.4%,11.8% and 33.3%,P=0.016) and (12.3%,18.7% and 47.5%,P=0.002).Conclusions HLA mismatch will not significantly impact the engraftment or 2-year survival after UR-PBSCT,but two mismatched HLA loci may

    Full Text Available Empirical antibiotics at the onset of febrile neutropenia are one of several strategies for management of bacterial infections in patients undergoing Hematopoietic Stem Cell Transplant (HSCT (empiric strategy. Our HSCT program aims to perform HSCT in an outpatient setting, where an empiric antibiotic strategy was employed. HSCT recipients began receiving intravenous antibiotics at the onset of neutropenia in the absence of fever as part of our institutional policy from 01 Jan 2009; intravenous Prophylactic strategy. A prospective study was conducted to compare two consecutive cohorts [Year 2008 (Empiric strategy vs. Year 2009 (Prophylactic strategy] of patients receiving HSCT. There were 238 HSCTs performed between 01 Jan 2008 and 31 Dec 2009 with 127 and 111 in the earlier and later cohorts respectively. Infection-related mortality pre- engraftment was similar with a prophylactic compared to an empiric strategy (3.6% vs. 7.1%; p = 0.24, but reduced among recipients of autologous HSCT (0% vs. 6.8%; p = 0.03. Microbiologically documented, blood stream infections and clinically documented infections pre-engraftment were reduced in those receiving a prophylactic compared to an empiric strategy, (11.7% vs. 28.3%; p = 0.001, (9.9% vs. 24.4%; p = 0.003 and (18.2% vs. 33.9% p = 0.007 respectively. The prophylactic use of intravenous once-daily ceftriaxone in patients receiving outpatient based HSCT is safe and may be particularly effective in patients receiving autologous HSCT. Further studies are warranted to study the impact of this Prophylactic strategy in an outpatient based HSCT program.

    Adult patients with acute leukemia in need of a transplant but without a genoidentical donor are usually considered upfront for transplantation with stem cells from any other allogeneic source, rather than autologous stem cell transplantation. We used data from the European Society for Blood and Marrow Transplantation and performed a matched pair analysis on 188 T-cell-replete haploidentical and 356 autologous transplants done from January 2007 to December 2012, using age, diagnosis, disease status, cytogenetics, and interval from diagnosis to transplant as matching factors. "Haploidentical expert" centers were defined as having reported more than five haploidentical transplants for acute leukemia (median value for the study period). The median follow-up was 28 months. Multivariate analyses, including type of transplant categorized into three classes ("haploidentical regular", "haploidentical expert" and autologous), conditioning intensity (reduced intensity versus myeloablative conditioning) and the random effect taking into account associations related to matching, showed that non-relapse mortality was higher following haploidentical transplants in expert (HR: 4.7; P=0.00004) and regular (HR: 8.98; Ptransplants was lower in expert centers (HR:0.39; P=0.0003) but in regular centers was similar to that for autologous transplants. Leukemia-free survival and overall survival rates were higher following autologous transplantation than haploidentical transplants in regular centers (HR: 1.63; P=0.008 and HR: 2.31; P=0.0002 respectively) but similar to those following haploidentical transplants in expert centers. We conclude that autologous stem cell transplantation should presently be considered as a possible alternative to haploidentical transplantation in regular centers that have not developed a specific expert program.

    Purpose: To analyze, through chart review, the efficacy of salvage radiation therapy (sRT) for relapsed or progressive Hodgkin lymphoma (HL) patients who failed autologous stem cell transplant (ASCT). Patients and Methods: Among 347 patients with recurrent/refractory HL who received ASCT from 1986-2006, 163 had post-ASCT progression or relapse. Of these, 56 received sRT and form the basis of this report. Median age at sRT was 30 years (range, 17-59 years). Disease was confined to lymph nodes in 27 patients, whereas 24 had both nodal and extranodal disease. Salvage radiation therapy alone was given in 34 patients (61%), and sRT plus chemotherapy was given in 22 (39%). Median interval from ASCT to sRT was 0.8 years (range, 0.1-5.6 years). The median dose was 35 Gy (range, 8-40.3 Gy). The sRT technique was extended-field in 14 patients (25%) and involved-field in 42 (75%). Results: The median follow-up from sRT was 31.3 months (range, 0.2-205.5 months). Overall response rate was 84% (complete response: 36%; partial response: 48%). The median overall survival was 40.8 months (95% confidence interval, 34.2-56.3 months). The 5-year overall survival was 29% (95% confidence interval, 14%-44%). The 2-year progression-free survival (PFS) was 16%; the 2-year local PFS was 65%, whereas the 2-year systemic PFS was 17%. The 1-year PFS was higher in patients in whom all diseased sites were irradiated (49%) compared with those in whom only the symptomatic site was treated (22%, P=.07). Among 20 alive patients, 5 were disease free (at 6.4, 6.8, 7.4, 7.9, and 17.1 years). Conclusion: For patients with HL who fail ASCT, a selective use of RT provides a durable local control rate of 65% at 2 years and should be considered as part of the standard management plan for the palliation of incurable HL. Occasionally irradiation of truly localized disease can lead to long-term survival.

    T lymphocytes play a pivotal role in graft-versus-host disease (GVHD) and largely contribute to the graft-versus-leukemia (GVL) effect. Most mature T lymphocytes specifically recognize antigens through the alpha/beta T-cell receptor (TCR). Each alpha/beta TCR chain includes a constant region and a variable region, the latter being encoded by V-J alpha or V-D-J beta rearranged gene segments. To better characterize T cells involved in GVHD, V alpha and V beta gene segment usage was analyzed, after cDNA amplification, in peripheral blood mononuclear cells (PBMC) and skin samples from three patients with grade II cutaneous GVHD. At time of GVHD diagnosis (days 11, 22, and 25), when first signs of engraftment were detectable, virtually all V alpha and V beta subfamilies were represented in PBMC RNAs of the three recipients. These results suggest that diversified TCR gene segment expression is observed early after allogenic bone marrow transplantation (alloBMT). Lymphocytes infiltrating GVHD skin also expressed a large series of V alpha and V beta subfamily specificities. However, analysis of the V alpha and V beta amplified products showed substantial differences between PBMC and the skin lymphocyte RNAs. These observations indicate that a large variety of T lymphocytes are present at the disease site, while some of them may be specifically amplified or decreased in response to minor histocompatibility antigens (miHA). Further characterization of the latter T-cell subpopulations should lead to a better understanding of human in vivo responses directed at miHA.

    Full Text Available Levels of Kappa-deleting recombination excision circles (KRECs, T-cell receptor excision circles (TRECs, and T-cell repertoire diversity were evaluated in 1038 samples of 124 children with primary immunodeficiency, of whom 102 (54 with severe combined immunodeficiency and 48 with other types of immunodeficiency underwent hematopoietic stem cell transplantation. Twenty-two not transplanted patients with primary immunodeficiency were used as controls. Only data of patients from whom at least five samples were sent to the clinical laboratory for routine monitoring of lymphocyte reconstitutions were included in the analysis. The mean time of the follow-up was 8 years. The long-lasting posttransplantation kinetics of KREC and TREC production occurred similarly in patients with severe combined immunodeficiency and with other types of immunodeficiency and, in both groups, the T-cell reconstitution was more efficient than in nontransplanted children. Although thymic output decreased in older transplanted patients, the degree of T-cell repertoire diversity, after an initial increase, remained stable during the observation period. However, the presence of graft-versus-host disease and ablative conditioning seemed to play a role in the time-related shaping of T-cell repertoire. Overall, our data suggest that long-term B- and T-cell reconstitution was equally achieved in children with severe combined immunodeficiency and with other types of primary immunodeficiency.

Altogether 134 patients with 6 different diagnoses were identified. Their donors were KIR genotyped using the Luminex and the SSP techniques. The clinical endpoint, that is, occurrence of relapse, was compared with the presence or absence of single KIR genes. Also, time from transplantation to relapse was analyzed. The patients with AML whose donors have KIR2DL2 or KIR2DS2 had statistically significantly longer relapse-free survival (P=0.015. Our data support previous reports that donors with KIR B-haplotype defining genes have a lower occurrence of relapse in HSCT of AML patients. Determination of donor KIR haplotypes could be a useful addition for a risk assessment of HSCT especially in AML patients.

    Disseminated Cryptococcus disease occurs in patients with defective T-cell immunity. Cryptococcal meningitis following autologous stem cell transplant (SCT) has been described previously in only 1 patient, 4 months post SCT and while off antifungal prophylaxis. We present a unique case of Cryptococcus meningitis pre-engraftment after autologous SCT, while the patient was receiving fluconazole prophylaxis. A 41-year-old man with non-Hodgkin's lymphoma underwent autologous SCT. Post-transplant prophylaxis consisted of fluconazole 400 mg daily, levofloxacin 500 mg daily, and acyclovir 800 mg twice daily. On day 9 post transplant, he developed fever and headache. Peripheral white blood cell count (WBC) was 700/μL. Magnetic resonance imaging of the brain showed lesions consistent with meningoencephalitis. Cerebrospinal fluid (CSF) analysis revealed a WBC of 39 with 77% lymphocytes, protein 63, glucose 38, CSF pressure 20.5 cmH2 O, and a positive cryptococcal antigen. CSF culture confirmed Cryptococcus neoformans. The patient was treated with liposomal amphotericin B 5 mg/kg intravenously daily, and flucytosine 37.5 mg/kg orally every 6 h. He was switched to fluconazole 400 mg daily after 3 weeks of amphotericin therapy, with sterilization of the CSF with negative CSFCryptococcus antigen and negative CSF culture. Review of the literature revealed 9 cases of cryptococcal disease in recipients of SCT. Median time of onset was 64 days post transplant. Only 3 meningitis cases were described; 2 of them after allogeneic SCT. Fungal prophylaxis with fluconazole post autologous SCT is recommended at least through engraftment, and for up to 100 days in high-risk patients. A high index of suspicion is needed to diagnose and treat opportunistic infections, especially in the face of immunosuppression and despite adequate prophylaxis. Infection is usually fatal without treatment, thus prompt diagnosis and therapy might be life saving.

    Older recipient and donor age were associated with higher incidences of severe graft-versus-host disease (GVHD) and mortality after allogeneic hematopoietic stem cell transplantation from matched sibling donors (MSDs) and matched unrelated donors. Since a lower incidence of severe GVHD is advantageous in unrelated cord blood transplantation (CBT), a higher incidence of GVHD using older MSDs could be overcome using cord blood for older patients. We retrospectively analyzed Japanese registration data of 2,091 patients with acute myeloid leukemia, acute lymphoblastic leukemia (ALL), and myelodysplastic syndrome aged 50 years or older who underwent MSD bone marrow transplantation (BMT) (n = 319), MSD peripheral blood stem cell transplantation (PBSCT) (n = 462), or unrelated CBT (n = 1,310) between 2007 and 2012. Median age of MSD was 56 (range, 38-74) years. Compared with CBT, the risk of developing extensive chronic GVHD was higher after BMT (hazard ratio [HR], 2.00; P = 0.001) or PBSCT (HR, 2.38; P transplant-related mortality was lower after BMT (HR, 0.61; P < 0.001) or PBSCT (HR, 0.63; P < 0.001). Relapse rates were not significant difference between three groups. Although overall mortality was lower after BMT (HR, 0.67; P < 0.001) or PBSCT (HR, 0.75; P = 0.002) compared with CBT, the rates of a composite endpoint of GVHD-free, relapse-free survival (GRFS) were not significant difference between three groups. These data showed that MSDs remain the best donor source for older patients, but CBT led to similar GRFS to BMT and PBSCT.

    Allogeneic hematopoietic stem cell transplantation and solid organ transplantation have become established treatments offered to patients for whom there are otherwise no curative treatment options. Unfortunately, these therapeutic modalities are associated with severe complications that limit its applicability. Alloimmunity is an important cause of morbidity and mortality after both organ transplantation and allogeneic hematopoietic stem cell transplantation and represents a major barrier to the more wide-spread use of these treatment modalities. Statins are a class of lipid-lowering drugs, which also posses immunomodulatory effects. Results from preclinial research and early-stage clinical studies indicate that treatment with statins could be beneficial for the prevention and treatment of graft-versus-host disease and transplant rejection. In addition to preventing graft-versus-host disease or graft rejection statins possess several other effects that might prove beneficial in the setting of transplantation, such as cardiovascular protection and antineoplastic activity. Here we summarize the current knowledge about the immunomodulatory effects of statins and discuss the clinical implications for their use in patients undergoing stem cell transplantation or solid organ transplantation.

    Full Text Available Abstract Background Stem cell transplant has been utilized in the treatment of malignancies and rheumatic disease. Rheumatic disease may be transferred from the donor with active disease or may be developed in a recipient de novo as a late complication of SCT. Case Presentation We here report the rare case of a 26-year old male patient, who has been diagnosed with undifferentiated spondyloarthropathy after unique circumstance. The patient suffered from intermittent inflammatory back pain and peripheral joint swelling for several years and did not find relief through multiple emergency room visits at different medical facilities. After a thorough history and physical exam, it was noted that our patient had developed signs of axial disease along with dactylitis and overall that he had been insidiously developing an undifferentiated spondyloarthopathy after allogeneic stem cell transplantation. Conclusion Our observation supports the hypothesis that de novo rheumatic disease can develop after stem cell transplant for a variety of reasons. Thus, larger studies and awareness of this association are needed to delineate the exact underlying mechanism(s.

The number of patients receiving AHSCT is increasing due to new indications, and more elderly patients with comorbidities are included in the protocols. Survival of the patients undergoing AHSCT has improved owing to better patient care, including optimization of transfusion support, which has a major contribution. However, transfusion can also be hazardous. Increasing awareness about transfusion and finding the balance between avoiding unnecessary transfusions and transfusing the correct component when needed are the key issues. Myeloablative conditioning results in pancytopenia, and the patients are prone to infections, anemia, and bleeding both before and after transplantation. Until red cell and platelet engraftment, the patients are usually transfusion dependent needing red cell and/or platelet components. Physicians dealing with AHSCT patients should be well informed about the attributes of the blood components they order. Knowledge about transfusion indications, triggers, and how to prevent and manage eventual transfusion complications is also required. The clinical picture can be challenging, and transplantation/treatment-related toxicity/complications can sometimes be difficult to distinguish from a transfusion complication, especially if the latter one took place, for instance, several days or weeks ago. ABO compatibility between the patient and the donor is not a prerequisite when choosing human leukocyte antigen-matched hematopoietic stem cell donor. Consequently, ABO incompatibility exists in ~40% of the cases and brings some immunohematological issues

    Lenalidomide (Revlimid(®)) is a second-generation immunomodulatory drug structurally related to thalidomide, with improved efficacy and tolerability, for which the label in the EU was recently expanded to include continuous therapy in patients with previously untreated multiple myeloma not eligible for stem-cell transplantation. In randomized, controlled clinical trials, continuous lenalidomide therapy, either in combination with dexamethasone (FIRST trial) or as maintenance monotherapy following induction with melphalan/prednisone/lenalidomide (MM-015 trial), significantly improved progression-free survival (PFS) compared with induction therapy alone (with non-lenalidomide- or lenalidomide-containing regimens) in patients with newly diagnosed multiple myeloma not eligible for stem-cell transplantation. The improvements in PFS with continuous lenalidomide were reflected in improved health-related quality-of-life measures. An overall survival benefit was observed in the FIRST trial, but not in the MM-015 trial. Continuous lenalidomide and continuous thalidomide regimens displayed similar efficacy, but lenalidomide was associated with significantly less toxicity than thalidomide. Continuous use of lenalidomide did not appear to negatively impact on the drug's tolerability and did not increase the incidence of neutropenia or second primary malignancy compared with shorter-term use. The incidence of most adverse events began to reduce after about 18 months of therapy. In conclusion, continuous lenalidomide regimens provide an effective longer-term treatment option in patients with newly diagnosed multiple myeloma ineligible for stem-cell transplantation.

    Since 1928, human fetal tissues and stem cells have been used worldwide to treat various conditions. Although the transplantation of the fetal midbrain substantia nigra and dopaminergic neurons in patients suffering from Parkinson's disease is particularly noteworthy, the history of other types of grafts, such as those of the fetal liver, thymus, and pancreas, should be addressed as there are many lessons to be learnt for future stem cell transplantation. This report describes previous practices and complications that led to current clinical trials of isolated fetal stem cells and embryonic stem (ES) cells. Moreover, strategies for transplantation are considered, with a particular focus on donor cells, cell processing, and the therapeutic cell niche, in addition to ethical issues associated with fetal origin. With the advent of autologous induced pluripotent stem cells and ES cells, clinical dependence on fetal transplantation is expected to gradually decline due to lasting ethical controversies, despite landmark achievements.

    2008-05-01

    We are reporting the case of a 17-year-old girl with kidney transplant under immunosuppressive treatment. Evidences of transplant malfunction led to urinary cytology to rule out BKV infection. The smears showed the presence of koilocytes. Gynecologic examination revealed numerous condylomatous lesions in the vulva, vagina, and cervix. PAP smears showed cells with moderate to severe koilocytic dysplasia. PCR performed on material retrieved from both the smears showed HPV18 DNA sequences. Koilocytes have rarely been documented in urinary cytologic examination. Since post-transplant immunosuppressed patients are prone to develop florid and extensive HPV infections, urinary cytology may prove useful for routine search of cells with this virus cytopathic effect.

    Stem cells have the ability to divide for indefinite periods in culture and to give rise to specialized cells. Cord blood as a source of hematopoietic stem cells (HSC) has several advantages as it is easily available, involves non-invasive collection procedure and is better tolerated across the HLA barrier. Since the first cord blood transplant in 1988, over 2500 cord blood HSC transplants have been done world wide. Since then, the advantages of cord blood as a source of hematopietic stem cells for transplantation have become clear. Firstly, the proliferative capacity of HSC in cord blood is superior to that of cells in bone marrow or blood from adults. A 100 ml unit of cord blood contains 1/10th the number of nucleated cells and progenitor cells (CD34+ cells) present in 1000 ml of bone marrow, but because they proliferate rapidly, the stem cell in a single unit of cord blood can reconstitute the entire haematopoietic system. Secondly, the use of cord blood reduces the risk of graft vs host disease. Cord Blood Stem Cell banks have been established in Europe and United States to supply HSC for related and unrelated donors. Currently, more than 65,000 units are available and more than 2500 patients have received transplants of cord blood. Results in children have clearly shown that the number of nucleated cells in the infused cord blood influences the speed of recovery of neutrophils and platelets after myeloablative chemotherapy. The optimal dose is about 2 x 10(7) nucleated cells/kg of body weight. The present study was carried out for collection, separation, enumeration and cryopreservation of cord blood HSC and establishing a Cord Blood HSC Bank. 172 samples of cord blood HSC were collected after delivery of infant prior to expulsion of placenta. The average cord blood volume collected was 101.20 ml. Mononuclear cell count ranged from 7.36 to 25.6 x 10(7)/ml. Viability count of mononuclear cells was 98.1%. After 1 year of cryopreservation, the viability count on

    Rothia muciloginosa is a member of normal flora and rarely causes invasive disease. Immunosupressed patients have increased risk for severe infection. Here, we report a male patient with relapsed neuroblastoma hospitalized for pneumonia. After clinical improvement, patient's respiratory symptoms worsened again. Rothia muciloginosa was isolated from blood culture. The worsening of respiratory symptoms can be explained by hematogenous spread of bacteria. He was successfully treated with meropenem and vancomycin for 14 days. This rarely seen bacterium is known to have high mortality rates unless treated appropriately and should be considered especially in patients with malignancy due to their immunsupressed situation.

    Full Text Available To evaluate if WT1 expression may predict relapse after allo-SCT, we analyzed WT1 levels on peripheral blood (PB and bone marrow (BM before and after allo-SCT in 24 AML patients with WT1 overexpression at diagnosis. Five copies of WT1/ABL × 104 from PB were identified as the threshold value that correlated with relapse after allo-SCT. The same correlation was not identified when WT1 expression was assessed from bone marrow (BM. Eight out of 11 (73% patients with a pre-allo-SCT PB-WT1 ≥ 5 and 4/13 (31% patients with a pre-allo-SCT PB-WT1 < 5 relapsed, respectively (P = 0.04. The incidence of relapse was higher in patients with PB-WT1 ≥ 5 measured after allo-SCT, at the 3rd (56% versus 38%; P = 0.43 and at the 6th month (71% versus 20%; P = 0.03. Patients with pretransplant PB-WT1 < 5 had significantly better 2-year OS and LFS than patients with a PB-WT1 ≥ 5 (81% versus 0% and 63% versus 20% (P = 0.02. Our data suggest the usefulness of WT1 monitoring from PB to predict the relapse in allotransplanted AML patients and to modulate the intensity of conditioning and/or the posttransplant immunosuppression in an attempt to reduce the posttransplant relapse risk.

    Full Text Available There are few data available regarding the prevalence of infection in multiple myeloma (MM patients in conjunction with newer generations of immunomodulatory drugs (thalidomide, bortezomib, lenalidomide or post autologous stem cell transplantation.  We retrospectively analyzed 47 patients with MM from March 2006 to June 2009 at our institution. All patients received thalidomide and steroid therapy for at least 6 months. Nine patients received bortezomib and 11 lenalidomide subsequently to thalidomide, because of disease progression and 22 patients underwent autologous stem cell transplantation.   The median age was 64 years (range 37-86, with a female–to-male ratio of 18:29. The median residual-serum IgG-level at time of infection was 3.2 g/L, IgA 0.3 g/L and IgM 0.2 g/L. Most patients suffered from recurrent moderate to severe infections. All patients except 3 received intravenous immunoglobulin (IVIG therapy with a significant decline of the rate of infection thereafter. Our analysis shows that IVIG appears to be an effective strategy to prevent infection in MM patients. Further studies to confirm these findings are warranted.

    Full Text Available Due to its negative impact in the outcome of stem cell transplant (SCT and solid organ transplant patients (SOT CMV has been called “the troll of transplantation”. One of the greatest advances in the management of SCT has been the introduction of the preemptive strategy. Since its introduction, the incidence of the viremia, as expected, remains unchanged but there has been a marked decline in the incidence of early CMV disease. But in spite of the advances in prevention of CMV disease, CMV is still today an important cause of morbidity and mortality. Late CMV disease is still occurring in a significant proportion of patients and the so-called indirect effects of CMV are causing significant morbidity and mortality. Fortunately, there have been several advances in the development of new antivirals, adoptive immunotherapy and DNA-CMV vaccines that might transform the management of CMV in the near future.

    HBV-DNA integration frequently occurs in HBV-related hepatocellular carcinoma (HCC), but whether HBV antigens are expressed in HCC cells and can be targeted by immune therapeutic strategies remains controversial. Here, we first characterized HBV antigen expression in HCC metastases, occurring in a patient who had undergone liver transplantation for HBV-related HCC. We then deployed for the first time in HCC autologous T cells, genetically modified to express an HBsAg specific T cell receptor, as therapy against chemoresistant extrahepatic metastases. We confirmed that HBV antigens were expressed in HCC metastases (but not in the donor liver) and demonstrated that tumour cells were recognized in vivo by lymphocytes, engineered to express an HBV-specific T cell receptor (TCR). Gene-modified T cells survived, expanded and mediated a reduction in HBsAg levels without exacerbation of liver inflammation or other toxicity. Whilst clinical efficacy was not established in this subject with end-stage metastatic disease, we confirm the feasibility of providing autologous TCR-redirected therapy against HCC and advocate this strategy as a novel therapeutic opportunity in hepatitis B-associated malignancies.

    Pneumocystis jirovecii can cause life-threatening pneumonia following treatment for haematological malignancies or after HSCT. The mortality rate of P. jirovecii pneumonia (PCP) in these patients is 30%-60%, especially after HSCT. The clinical presentation of PCP in haematology differs from that associated with HIV infection, with the disease being acute and more often severe, having a lower fungal burden and being more frequently linked to treatment with corticosteroids. Most cases occur in patients not receiving adequate prophylaxis. The development of new therapies, including targeted treatments and monoclonal antibodies in various haematological diseases, justifies constant vigilance in order to identify new at-risk populations and give prophylaxis accordingly. The fifth and sixth European Conferences on Infections in Leukaemia (ECIL-5 and ECIL-6) aimed to review risk factors for PCP in haematology patients and to establish evidence-based recommendations for PCP diagnosis, prophylaxis and treatment. This article focuses on the magnitude of the problem, the main differences in clinical presentation between haematology patients and other immunocompromised populations, especially HIV-infected patients, and the main risk factors.

    Full Text Available Diabetes mellitus is one of the most important causes of chronic kidney disease (CKD. In patients with advanced diabetic kidney disease, kidney transplantation (KT with or without a pancreas transplant is the treatment of choice. We aimed to review current data regarding kidney and pancreas transplant options in patients with both type 1 and 2 diabetes and the outcomes of different treatment modalities. In general, pancreas transplantation is associated with long-term survival advantages despite an increased short-term morbidity and mortality risk. This applies to simultaneous pancreas kidney transplantation or pancreas after KT compared to KT alone (either living donor or deceased. Other factors as living donor availability, comorbidities, and expected waiting time have to be considered whens electing one transplant modality, rather than a clear benefit in survival of one strategy vs. others. In selected type 2 diabetic patients, data support cautious utilization of simultaneous pancreas kidney transplantation when a living kidney donor is not an option. Pancreas and kidney transplantation seems to be the treatment of choice for most type 1 diabetic and selected type 2 diabetic patients.

    The aim of the study was to determine the diagnostic performance of {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT for the detection and localization of residual or recurrent disease in patients with multiple myeloma (MM) after stem cell transplantation. A total of 197 whole-body {sup 18}F-FDG PET/CT scans were performed in 99 patients with MM at different time points in the course of disease after autologous or allogeneic stem cell transplantation. Post-transplant PET/CT scans and clinical remission status as determined by the clinical gold standard (Uniform Response Criteria) were analysed and compared. A total of 576 focal osseous and extramedullary lesions were detected in 79 scans. Additional diffuse bone marrow involvement was detected in 17 patients. {sup 18}F-FDG PET/CT had a sensitivity of 54.6%, a specificity of 82.1%, a positive predictive value of 82.3%, a negative predictive value of 54.2% and an overall accuracy of 65.5%. The sensitivity of {sup 18}F-FDG PET/CT was shown to depend on the disease category according to the Uniform Response Criteria for myeloma. In patients with MM in the post-transplant setting, {sup 18}F-FDG PET/CT may (1) contribute to the detection and localization of disease, (2) provide information about the extent of distinct myeloma manifestations and the total disease burden and (3) add information about the metabolic activity of disease, but (4) has substantially lower sensitivity for this purpose compared to the pretreatment setting.

    Since the introduction of reduced-intensity stem-cell transplantation (RIST), allogeneic stem-cell transplantation has become available for elderly patients. While pharmacokinetics of cyclosporine might differ according to age or other factors, cyclosporine is uniformly started at an oral dose of 6 mg/kg/day. We retrospectively reviewed medical records of 35 patients aged between 32 and 65 (median 52) years who had undergone RIST. Doses of cyclosporine were adjusted to the target blood trough level of 150-250 ng/ml. Cyclosporine dosages were changed in 33 patients (94%). Dose reduction was required in 32 patients because of high blood levels (n=25), renal dysfunction (n=3), hepatic dysfunction (n=2), and hypertension (n=2). Cyclosporine doses were increased in one because of the suboptimal level. The median of the achieved stable doses was 3.1 mg/kg/day (range, 1.0-7.4). Five patients sustained Grade III toxicities according to NCI-CTC version 2.0: renal dysfunction (n=4), hyperbilirubinemia (n=2), and hypertension (n=2). No patients developed grade IV toxicity. There was no statistically significant difference in the frequency and severity of cyclosporine toxicities between patients aged 50 years and above and those below 50 years. The initial oral cyclosporine dose of 6 mg/kg/day was unnecessarily high irrespective of age. The possible overdose of cyclosporine might have aggravated regimen-related toxicities.

    To investigate the impact of exercise on adult allogeneic hematopoietic cell transplant recipients, we randomized 100 patients to either a structured walking regimen or to a control group with no formal exercise program. Starting on the day of admission for transplant, patients in the exercise arm were asked to walk on a treadmill twice a day for 15 minutes while in the hospital. After discharge, they were asked to walk once a day for 30 minutes. The effect of the exercise program was primarily measured by the change in the Karnofsky score (KPS) from transplant admission to day 100 posttransplant, which was scored by the attending physician who was blinded to the assigned exercise regimen. The decline in KPS was smaller in the exercise group than in the control group: 10 points versus 20 points. This difference was not statistically significant in the total study population (P=.21) but was statistically significant among the subset of older and less fit patients receiving nonmyeloablative pretransplant conditioning (P=.04). Sixty-four percent of patients on the exercise arm who had a baseline KPSor=90 by day 100 compared to 18% of the control arm (P=.03). Thirty-two percent of patients with a baseline score>or=90 had a score>or=90 by day 100 in both groups (P=.99). Analyses of patients' self reported scores at the time of discharge for physical and emotional well-being showed that the exercise arm had better scores for physical well-being (Ppatients, scores for physical and emotional well-being were both higher in the exercise arm (P=.02). Length of hospitalization and survival were not different between the 2 study arms. We conclude that assignment of a structured walking regimen to patients can lead to better physical performance during the recovery period and by patient assessment, a better perceived physical and emotional state. In addition, exercise has a greater impact among patients who are less fit coming into transplant. Structured exercise may have a

    Background Hodgkin's lymphoma has high rates of cure, but in 15% to 20% of general patients and between 35% and 40% of those in advanced stages, the disease will progress or will relapse after initial treatment. For this group, hematopoietic stem cell transplantation is considered one option of salvage therapy. Objectives To evaluate a group of 106 patients with Hodgkin's lymphoma, who suffered relapse or who were refractory to treatment, submitted to autologous hematopoietic stem cell transplantation in a single transplant center. Methods A retrospective study was performed with data collected from patient charts. The analysis involved 106 classical Hodgkin's lymphoma patients who were consecutively submitted to high-dose chemotherapy followed by autologous transplants in a single institution from April 1993 to December 2006. Results The overall survival rates of this population at five and ten years were 86% and 70%, respectively. The disease-free survival was approximately 60% at five years. Four patients died of procedure-related causes but relapse of classical Hodgkin's lymphoma after transplant was the most frequent cause of death. Univariate analysis shows that sensitivity to pre-transplant treatment and hemoglobin < 10 g/dL at diagnosis had an impact on patient survival. Unlike other studies, B-type symptoms did not seem to affect overall survival. Lactic dehydrogenase and serum albumin concentrations analyzed at diagnosis did not influence patient survival either. Conclusion Autologous hematopoietic stem cell transplantation is an effective treatment strategy for early and late relapse in classical Hodgkin's lymphoma for cases that were responsive to pre-transplant chemotherapy. Refractory to treatment is a sign of worse prognosis. Additionally, a hemoglobin concentration below 10 g/dL at diagnosis of Hodgkin's lymphoma has a negative impact on the survival of patients after transplant. As far as we know this relationship has not been previously reported

    Autologous hematopoietic cell transplantation (AHCT) as initial therapy of patients with multiple myeloma (MM) improves survival. However, data to support this approach for relapsed/progressive disease after initial AHCT (AHCT1) are limited. Using Center for International Blood and Marrow Transplant Research data, we report the outcomes of 187 patients who underwent a second AHCT (AHCT2) for the treatment of relapsed/progressive MM. Planned tandem AHCT was excluded. Median age at AHCT2 was 59 years (range, 28 to 72), and median patient follow-up was 47 months (range, 3 to 97). Nonrelapse mortality after AHCT2 was 2% at 1 year and 4% at 3 years. Median interval from AHCT1 to relapse/progression was 18 months, and median interval between transplantations was 32 months. After AHCT2, the incidence of relapse/progression at 1 and 3 years was 51% and 82%, respectively. At 3 years after AHCT2, progression-free survival was 13%, and overall survival was 46%. In multivariate analyses, those relapsing ≥36 months after AHCT1 had superior progression-free (P = .045) and overall survival (P = .019). Patients who underwent AHCT2 after 2004 had superior survival (P = .026). AHCT2 is safe and feasible for disease progression after AHCT1. In this retrospective study, individuals relapsing ≥36 months from AHCT1 derived greater benefit from AHCT2 compared with those with a shorter disease-free interval. Storage of an adequate graft before AHCT1 will ensure that the option of a second autologous transplantation is retained for patients with relapsed/progressive MM. PMID:23298856

    Heart failure is becoming a major issue for public health in western countries and the effect of currently available therapies is limited. Therefore cell transplantation was developed as an alternative strategy to improve cardiac structure and function. This review describes the multiple cell types and clinical trials considered for use in this indication. Most studies have been developed in models of post-ischemic heart failure. The transplantation of fetal or neonatal cardiomyocytes has proven to be functionally successful, but ethical as well as immunological and technical reasons make their clinical use limited. Recent reports, however, suggested that adult autologous cardiomyocytes could be prepared from stem cells present in various tissues (bone marrow, vessels, adult heart itself, adipose tissue). Alternatively, endothelial progenitors originating from bone marrow or peripheral blood could promote the neoangiogenesis within the scar tissue. Hematopietic stem cells prepared from bone marrow or peripheral blood have been proposed but their differentiation ability seems limited. Finally, the transplantation of skeletal muscle cells (myoblasts) in the infarcted area improved myocardial function, in correlation with the development of skeletal muscle tissue in various animal models. The latter results paved the way for the development of a first phase I clinical trial of myoblast transplantation in patients with severe post-ischemic heart failure. It required the scale-up of human cell production according to good manufacturing procedures, started in june 2000 in Paris and was terminated in november 2001, and was followed by several others. The results were encouraging and prompted the onset of a blinded, multicentric phase II clinical trial for skeletal muscle cells transplantation. Meanwhile, phase I clinical trials also evaluate the safeness and efficacy of various cell types originating from the bone marrow or the peripheral blood. However, potential side

    Full Text Available Natural killer cells at day 15 (NK-15, after autologous peripheral blood hematopoietic stem cell transplantation (APHSCT, is a prognostic factor for overall survival (OS and progression-free survival (PFS in non-Hodgkin lymphoma (NHL. The potential role of the immunologic (homeostatic environment affecting NK-15 recovery and survival post-APHSCT has not been fully studied. Therefore, we evaluate prospectively the cytokine profile in 50 NHL patients treated with APHSCT. Patients with an interleukin-15 (IL-15≥76.5 pg/mL at day 15 post-APHSCT experienced superior OS and PFS compared with those who did not; median OS; not reached versus 19.2 months, P<.002; and median PFS; not reached versus 6.8 months, P<.002, respectively. IL-15 was found to correlate with (rs=0.7, P<.0001 NK-15. Multivariate analysis showed only NK-15 as a prognostic factor for survival, suggesting that the survival benefit observed by IL-15 is most likely mediated by enhanced NK cell recovery post-APHSCT.

    Disease relapse still greatly interferes with the success of allogeneic hematopoietic stem cell transplantation (HSCT) for acute lymphoblastic leukemia (ALL). This study retrospectively evaluated the long-term safety and efficacy of a conditioning regimen consisting of total body irradiation (TBI; 12 Gy), cyclophosphamide (CY; 60 mg kg(-1) , two doses), and high-dose cytarabine (Ara-C; 2 g m(-2) ; four doses) for patients with ALL. Fifty-five patients (median age: 31-years old) were evaluated. Stem cells were from human leukocyte antigen-identical siblings in 22 patients and from alternative donors in 33. There were no cases of early death before engraftment, and 100-day transplant-related mortality was 7.3%. With a median follow-up period of 9.6 years, 5-year overall and disease-free survival were 63.2% (95% CI: 46.5-79.9%) and 63.6% (95% CI: 47.1-80.1%) in patients with complete remission, respectively, both of which were significantly higher than the values of 27.3% (95% CI: 8.7-46.0%) and 22.7% (95% CI: 5.3-40.1%) for patients in advanced stages (P < 0.01). These results suggest that TBI and CY (TBI-CY) plus Ara-C could be a feasible and effective conditioning regimen for adult patients with ALL both in remission and in advanced stages, and a future study to compare this combination therapy with TBI-CY is required.

    Acute graft-versus-host disease (aGVHD) is a major complication associated with allogeneic hematopoietic stem cell transplantation (allo-HSCT). Interleukin (IL)-35 is a novel anti-inflammatory cytokine that suppresses the immune response. This prospective study explored IL-35 plasma levels in 65 patients after HSCT. The results revealed that the peripheral blood of patients with grades III-IV aGVHD (23.46 ng/ml) had reduced IL-35 compared to transplanted patients with grades I-II aGVHD (40.26 ng/ml, p IL-35 levels with respect to aGVHD. The patients who received lower levels of IL-35 cells in the GBM (28.0 ng/ml, p = 0.551) or lower levels of IL-35 in PBPC (53.46 ng/ml, p = 0.03) exhibited a higher incidence of aGVHD. Patients with aGVHD have increased platelet aggregation. IL-35 was added to patient blood in vitro, and platelet aggregation was inhibited by IL-35 in a dose-dependent manner. The markers of platelet activation (CD62P/PAC-1) can also be inhibited by IL-35. The results indicate that IL-35 may affect the development of aGVHD by inhibiting platelet activation and aggregation. Our data suggests that IL-35 represents a potentially effective therapeutic agent against aGVHD after allo-HSCT.

    Full Text Available OBJECTIVE: To evaluate the vessel involvement and the role of multidedector computed tomograpy (MDCT in the early diagnosis of invasive pulmonary aspergillosis (IPA at MDCT in autologous bone morrow transplantation patients with febrile neutropenia and antibiotic-resistant fever of unknown origin with clinically suspected IPA. METHODS: 74 pulmonary MDCT examinations of 37 consecutive hematopoietic stem cell transplantation patients with febrile neutropenia with clinically suspected IPA were retrospectively evaluated. RESULTS: The diagnosis of IPA was made according to according to the Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Consensus Group criteria and 0, 14, 11 patients were diagnosed as proven, probable, possible IPA, respectively. Among 25 cases accepted as probable and possible IPA, all patients had pulmonary MDCT findings consistent with IPA. Remaining 12 patients were accepted as having fever of unknown origin (FUO and in these 12, MDCT showed patent vessel. In patients with probable/possible IPA, 72 focal pulmonary lesions were detected. In 41 of 72 (57%, vascular occlusion was detected. The CT halo sign was present in 25 of 41 (61% lesions. A clinical improvement, resolution of fever was observed following antifungal therapy in 19 (76% of 25 patients with probable/possible IPA. Six (25% patients diagnosed as IPA died during follow-up. Transplant related mortality at day 100 in patients with IPA and FUO were found to be 24% and 0%, respectively. CONCLUSION: In conclusion, MDCT has a potential role in early diagnosis of IPA by detection of vessel occlusion.

    Full Text Available Abstract Background Acute myeloid leukaemia (AML with 17p abnormalities (abn(17p carries a very poor prognosis due to high refractoriness to conventional chemotherapy, and allogeneic stem cell transplantation (allo-SCT appears as the only potential curative option. Methods To address outcomes after allo-SCT in patients with abn(17p, we retrospectively analysed de novo or secondary AML undergoing SCT between 2000 and 2013 from the EBMT registry. Results One hundred thirty-nine patients with confirmed abn(17p have been selected. At the time of transplant, one hundred twenty-five were in first remission (CR1. Median age was 54 years old. Abn(17p was associated with a monosomal karyotype in 83% of patients, complex karyotype in 91%, monosomy 5 or 5q deletion (-5/5q- in 55%, monosomy 7 (-7 in 39% and both -5/5q and -7 in 27%. Seventy-three patients (59% had a reduced-intensity conditioning regimen. The 2-year overall survival (OS and leukaemia-free survival (LFS were 28 and 24%, respectively. The 2-year non-relapse mortality (NRM was 15%, and 2-year relapse incidence (RI was 61%. The cumulative incidence of grade II to IV acute graft-versus-host disease (GvHD was 24% and that of chronic GvHD was 21%. In multivariate analysis, the presence of a -5/5q- in addition to abn(17p was significantly and independently associated with worse OS, LFS and higher RI. Age and donor types did not correlate with outcome. Conditioning intensity was not statistically associated with OS, LFS and NRM when adjusted for patients’ age. Conclusions In contrast to the dismal prognosis reported for AML patients harbouring abn(17p undergoing conventional chemotherapy, allogeneic SCT provides responses in about 25% of those patients transplanted in CR1.

    Full Text Available Haploidentical related donors are alternative stem cell sources for patients without human leukocyte antigen (HLA-matched related or unrelated donors. Immediate access to the donor, availability for patients with rare haplotypes, ease of stem cell procurement, and lack of a requirement for a physical cord blood bank or an extensive HLA database render this type of hematopoietic stem cell transplantation particularly attractive despite the high histoincompatibility barrier between the recipient and the haploidentical graft. In this review, we answer the following questions: 1 What are the current transplant strategies used to overcome the histoincompatibility barrier in haploidentical stem cell transplantation and their clinical results? 2 How should we choose the donor when there is more than one available haploidentical donor? 3 How does transplantation from haploidentical donors compare to that from umbilical cord blood?

    Full Text Available Objective: This study aimed to determine the current state of antifungal prophylaxis in Turkish stem cell transplantation (SCT centers. Materials and Methods: The were 38 active stem cell transplantation centers in Turkey, 28 of which were registered with the European Group for Blood and Marrow Transplantation (EBMT. Survey questionnaires were sent to the 28 EBMT centers in an effort to collect data on antifungal prophylaxis in different settings. In all, 24 of the centers completed the survey; 1 of the 24 centers was excluded from the study, as it was under construction at the time and was not performing transplantation.Results: In all, 15 (65% of the 23 centers were adult SCT centers, 7 (31% were pediatric SCT centers, and 1 center treated both adult and pediatric patients. All centers (23/23 performed both allogeneic and autologous transplants, 20 centers performed non-myeloablative transplants, 8 performed cord blood transplants, and 7 performed unrelated transplants. Primary antifungal prophylaxis was used at all 23 centers during allogeneic transplants, whereas 18 of the 23 centers used it during every autologous transplant and 2 of the 23 centers used it during autologous transplants on a per case basis. The most common drug used for prophylaxis was fluconazole (F (21/23, followed by itraconazole (I (3/23, amphotericin-B (2/23, and posaconazole (1/23. Among the 23 centers, 3 reported that for allogenic transplants they changed the antifungal prophylactic in cases of graft versus host disease (GVHD, and 12 of the 23 centers reported that they changed the antifungal prophylactic in case of nearby construction. All 23 centers performed secondary prophylaxis. Conclusion: Antifungal prophylaxis for hematopoetic SCT patients was the standard protocol in the 23 centers included in the study, usually with such azoles as F. The introduction of posaconazole in Turkey and the potential approval of voriconazole for antifungal prophylaxis will

    Toxoplasmosis is an opportunistic infection caused by the parasite Toxoplasma gondii. The infection is severe and difficult to diagnose in patients receiving allogeneic hematopoietic stem cell transplantation (HSCT). Twelve patients receiving HSCT were monitored post-transplant, by qualitative PCR at the Children's Hospital S.A.M.I.C. "Prof. Dr. Juan P. Garrahan". The monitoring of these patients was defined by a history of positive serology for toxoplasmosis in the donor or recipient and because their hematologic condition did not allow the use of trimethoprim-sulfamethoxazole for prophylaxis. During the patients' monitoring, two of them with positive PCR results showed signs of illness by T. gondii and were treated with pyrimethamine-clindamycin. In two other patients, toxoplasmosis was the cause of death and an autopsy finding, showing negative PCR results. Four patients without clinical manifestations received treatment for toxoplasmosis because of positive PCR detection. In four patients there were no signs of toxoplasmosis disease and negative PCR results during follow-up. The qualitative PCR technique proved useful for the detection of toxoplasmosis reactivation in HSCT recipients, but has limitations in monitoring and making clinical decisions due to the persistence of positive PCR over time and manifestations of toxicity caused by the treatment.

    This retrospective study considered the outcomes of 181 patients with acute myeloid leukemia (AML) transplanted in second complete remission (CR2) between January 2005 and April 2012 and who received either a myeloablative autologous stem cell transplant (Auto-SCT; n = 82; median age: 48 years; median follow-up: 45 months) or an umbilical cord blood (UCB) allogeneic SCT (n = 99, median age: 46 years; median follow-up: 36 months; conditioning regimens: myeloablative n = 21, reduced n = 78; single unit n = 37, double units n = 62). Although the Auto group showed a significant better prognostic profile at transplant, with longer median interval between diagnosis and time of graft, higher incidence of good-risk cytogenetics and lower number of previously transplanted patients, 3-year OS and LFS were similar between both groups (Auto: 59 ± 6% vs. 50 ± 6%, P = 0.45; and 57 ± 6% vs. 46 ± 6%, P = 0.37). In multivariate analysis, UCB allo-SCT was associated with lower relapse incidence (HR: 0.3, 95% CI: 0.11-0.82, P = 0.02), but higher non-relapse mortality (NRM) (HR: 4.16; 95% CI: 1.46-11.9, P = 0.008). Results from this large study suggest that UCB allo-SCT provides better disease control than auto-SCT, which is especially important in the setting of high-risk disease. However, this disease control advantage is counterbalanced by higher toxicity, highlighting the need for novel approaches aiming to decrease NRM after UCB allo-SCT.

    Full Text Available Background. Systemic sclerosis (SSc is a multisystem disease characterized by cutaneous and visceral fibrosis. Face and mouth changes include telangiectasia, sicca syndrome, and thinning and reduction of mouth width (microcheilia and opening (microstomia. We applied autologous fat transplantation compared with autologous adipose-derived stromal cells (ADSCs injection to evaluate the clinical improvement of mouth opening. Methods. From February to May 2013 ten consecutive SSc patients were enrolled from the outpatient clinic of Plastic Surgery Department of Sapienza University of Rome. Patients were divided into two groups as follows: 5 patients were treated with fat transplantation and 5 patients received infiltration of ADSCs produced by cell factory of our institution. To value mouth opening, we use the Italian version of Mouth Handicap in Systemic Sclerosis Scale (IvMHISS. Mouth opening was assessed in centimetres (Maximal Mouth Opening, MMO. In order to evaluate compliance and physician and patient satisfaction, we employed a Questionnaire of Satisfaction and the Visual Analogic Scale (VAS performed before starting study and 1 year after the last treatment. Results and Conclusion. We noticed that both procedures obtained significant results but neither one emerged as a first-choice technique. The present clinical experimentation should be regarded as a starting point for further experimental research and clinical trials.

    Adult T-cell leukemia-lymphoma is a distinct type of peripheral T-cell lymphoma caused by human T-cell lymphotropic virus type I. Although allogeneic stem cell transplantation after chemotherapy is a recommended treatment option for patients with aggressive adult T-cell leukemia-lymphoma, there is no consensus about indications for allogeneic stem cell transplantation because there is no established risk stratification system for transplant eligible patients. We conducted a nationwide survey of patients with aggressive adult T-cell leukemia-lymphoma to construct a new large database that includes 1,792 patients aged 70 years or younger with aggressive adult T-cell leukemia-lymphoma who were diagnosed between 2000 and 2013 and received intensive first-line chemotherapy. We randomly divided patients into two groups (training and validation sets). Acute type, poor performance status, high soluble interleukin-2 receptor level (> 5,000 U/mL), high adjusted calcium level (≥ 12 mg/dL), and high C-reactive protein level (≥ 2.5 mg/dL) were independent adverse prognostic factors using the training set. We used these five variables to divide patients into three risk groups. In the validation set, medial overall survival was 626 days, 322 days, and 197 days for the low-, intermediate-, and high-risk groups, respectively. In the intermediate- and high-risk groups, transplanted recipients had significantly better overall survival than non-transplanted patients. We developed a new promising risk stratification system to identify patients aged 70 years or younger with aggressive adult T-cell leukemia-lymphoma who may benefit from upfront allogeneic stem cell transplantation. Prospective studies are warranted to confirm the benefit of this treatment strategy.

    Minimal residual disease (MRD) was monitored by Wilms tumor 1 (WT1) expression in 207 patients with acute myeloid leukemia (AML) after an allogeneic hemopoietic stem cell transplantation (HSCT) as a trigger to initiate pre-emptive immunotherapy (IT) with cyclosporin discontinuation and/or donor lymphocyte infusion. The trigger for IT was WT1 ≥ 180 copies/10(4) Abelson cells in marrow cells in the first group of 122 patients (WT1-180) and ≥ 100 copies in a subsequent group of 85 patients (WT1-100). Forty patients received IT. The cumulative incidence (CI) of relapse was 76% in WT1-180 (n = 17) versus 29% in WT1-100 patients (n = 23) receiving IT (P = .006); the leukemia-free survival from MRD positivity was 23% versus 74%, respectively (P = .003). We then looked at the entire AML patient population (n = 207). WT1-180 and WT1-100 patients were comparable for disease phase and age. The overall 4-year CI of transplantation-related mortality was 13% in both groups; the CI of leukemia relapse was 38% in the WT1-180 and 28% in the WT1-100 patients (P = .05) and leukemia-free survival was 56% versus 48%, respectively (P = .07). In conclusion, we suggests that WT1-based pre-emptive immunotherapy is feasible in patients with undergoing an allogeneic HSCT. The protective effect on relapse is greater when IT is triggered at lower levels of WT1.

    Full Text Available To investigate the impact of pre-transplant CMV serostatus of donor or recipient on outcome of patients undergoing allogeneic hematopoietic stem cell transplantation (Allo-SCT for Multiple Myeloma (MM. To our knowledge no data are available in the literature about this issue. We retrospectively followed 99 consecutive patients who underwent reduced-intensity conditioning (RIC Allo-SCT for MM in our cancer centre at Marseille between January 2000 and January 2012. Based upon CMV serostatus, patients were classified as low risk (donor [D]-/recipient [R]- 17 patients (17.1%, intermediate risk (D+/R 14 patients (14.1%, or high risk – either (D-/R+ 31 patients (31.3% or (D+/R+, 37 patients (37.3%. Cumulative incidence of CMV reactivation was 39% with a median time of 61 days (26–318. Three patients (3% developed CMV disease. Two factors were associated with CMV reactivation: CMV serostatus group (low: 0% vs intermediate: 29% vs high: 50%; p=0.001 and the presence of grade II–IV acute GvHD (Hazard Ratio: HR=2.1 [1.1–3.9]. Thirty-six of the 39 patients (92% with CMV reactivation did not present positive detection of CMV after a 21-day median duration preemptive treatment with ganciclovir. Cumulative incidence of day 100 grade II–IV acute GvHD, 1-year chronic GvHD and day 100 transplantation related mortality (TRM were 37%, 36% and 9%, respectively. CMV reactivation and serostatus were not associated with increased GvHD and TRM or short survival. Only the presence of acute GvHD as a time dependent variable was significantly associated with increased TRM (p=0.005. Two-year overall and progression free survival were 56% and 34%, respectively. Donor and recipient CMV serostatus and acute GvHD are independent factors for increased CMV reactivation in high-risk MM patients undergoing RIC Allo-SCT.

    Full Text Available Hodgkin lymphoma is one of the most curable human tumors. Despite this, about 30% of these patients relapsed or are primary refractory to the first line treatment. Autografting is generally considered the standard of care for these patients. Alternative salvage strategies have been evaluated such as high dose sequential and tandem autografting strategies. In younger patients,  refractory or early relapsed after autografting, allogeneic stem cell transplantation has been employed but this approach has been followed by significant concerns since the treatment related mortality often exceeded 40-50%, and relapses were not uncommon. It is clear that patient selection remains an issue in all allografting reports. At the end, new drugs and novel treatment strategies, that are based on our understanding of the disease biology and signaling pathways, are needed to improve treatment outcome for these patients. The two leading compounds Brentuximab Vedotin and Panobinostat, are currently under evaluation  in several clinical trials.

    Full Text Available Osteogenesis Imperfecta (OI can be a severe disorder that can be diagnosed before birth. Transplantation of mesenchymal stem cells (MSC has the potential to improve the bone structure, growth and fracture healing. In this review we give an introduction to OI and MSC, and the basis for prenatal and postnatal transplantation in OI. We also summarize the two patients with OI who has received prenatal and postnatal transplantation of MSC.The findings suggest that prenatal transplantation of allogeneic MSC in OI is safe. The cell therapy is of likely clinical benefit with improved linear growth, mobility and reduced fracture incidence. Unfortunately, the effect is transient. For this reason postnatal booster infusions using same-donor MSC have been performed with clinical benefit, and without any adverse events.So far there is limited experience in this specific field and proper studies are required to accurately conclude on clinical benefits of MSC transplantation to treat OI.

    Embryonic stem (ES) cells, which are derived from the inner cell mass of mammalian blastocyst stage embryos, have the ability to differentiate into any cell type in the body and to grow indefinitely while maintaining pluripotency. During development, cells undergo progressive and irreversible differentiation into specialized adult cell types. Remarkably, in spite of this restriction in potential, adult somatic cells can be reprogrammed and returned to the naive state of pluripotency found in the early embryo simply by forcing expression of a defined set of transcription factors. These induced pluripotent stem (iPS) cells are molecularly and functionally equivalent to ES cells and provide powerful in vitro models for development, disease, and drug screening, as well as material for cell replacement therapy. Since functional impairment results from cell loss in most central nervous system (CNS) diseases, recovery of lost cells is an important treatment strategy. Although adult neurogenesis occurs in restricted regions, the CNS has poor potential for regeneration to compensate for cell loss. Thus, cell transplantation into damaged or diseased CNS tissues is a promising approach to treating various neurodegenerative disorders. Transplantation of photoreceptors or retinal pigment epithelium cells derived from human ES cells can restore some visual function. Patient-specific iPS cells may lead to customized cell therapy. However, regeneration of retinal function will require a detailed understanding of eye development, visual system circuitry, and retinal degeneration pathology. Here, we review the current progress in retinal regeneration, focusing on the therapeutic potential of pluripotent stem cells.

    Syndrome of inappropriate anti-diuretic hormone (SIADH) has been reported to be associated with systemic Strongyloides stercoralis. Here, we report a case of a stem cell transplant (SCT) recipient who developed severe SIADH secondary to systemic S Stercoralis. The SIADH resolved quickly after treating the systemic S Stercoralis with ivermectin. A systematic review of the literature was performed by PubMed, Scopus, and Cochrane database search. Only eight cases of S Stercoralis in allogeneic SCT recipients have been previously reported. To our knowledge, ours is the first reported case of SIADH secondary to S Stercoralis infection in an allogeneic SCT recipient. Prior to transplantation, even if asymptomatic, patients from endemic regions should be screened with strongyloides immunoglobulin (Ig)G serology. Pretransplantation eosinophilia should be evaluated by screening multiple stool samples for ova and parasites. Transplant candidates with positive serology or stool tests can be treated pretransplantation to eradicate infection. Patients at risk for S Stercoralis who develop nonspecific gastrointestinal complaints, rash, pulmonary infiltrates, or gram-negative bacteremia or meningitis may have S Stercoralis hyperinfection syndrome. Our case indicates that the development of SIADH may be an additional clue to this diagnosis. Appropriate diagnostic studies, including repeat stool and other body fluid sampling, should be expedited and ivermectin therapy initiated rapidly to prevent significant morbidity and mortality.

    Full Text Available Abstract Background Allogeneic hematopoietic stem cell transplantation (allo-HSCT leads to a prolonged state of immunodeficiency and requires reconstitution of normal T-cell immunity. Signal joint T-cell receptor excision DNA circles (sjTRECs are markers of developmental proximity to the thymus that have been used to evaluate thymic function related to T-cell immune reconstitution after HSCT. To assess the proliferative history in different T-cell receptor beta variable region (TRBV subfamilies of T cells after HSCT, expansion of TRBV subfamily-naive T cells was determined by analysis of a series of TRBV-BD1 sjTRECs. Methods sjTRECs levels were detected by real-time quantitative polymerase chain reaction (PCR in peripheral blood mononuclear cells (PBMCs from 43 Chinese acute leukemia patients who underwent allo-HSCT. Twenty-three TRBV-BD1 sjTRECs were amplified by semi-nested PCR. Sixteen age-matched healthy volunteers served as normal controls. Results sjTRECs levels were low or undetectable in the first 6 weeks after allo-HSCT and increased after 8 weeks post HSCT; however, sjTRECs levels at week 20 post-HSCT were still less than normal controls. Frequencies of TRBV subfamily sjTRECs in PBMCs from recipients at week 8 post-HSCT (29.17 ± 20.97% or at week 16 post-HSCT (38.33 ± 9.03% were significantly lower than those in donors (47.92 ± 13.82% or recipients at pre-HSCT (45.83 ± 14.03%. However, frequencies of TRBV subfamily sjTRECs in recipients at week 30 post-HSCT (42.71 ± 21.62% were similar to those in donors and recipients at pre-HSCT. sjTRECs levels in donors had a positive linear correlation with sjTRECs levels in recipients within 8-12 weeks post-HSCT. Patients with acute graft-versus-host disease (GVHD or chronic GVHD had profoundly reduced TRECs levels during the first year post-HSCT. Frequencies of BV22-BD1 sjTRECs and BV23-BD1 sjTRECs in patients with GVHD were significantly lower than those in recipients at pre-HSCT, and the

    The availability of alternative sources of stem cells including most recently T-replete haploidentical marrow or peripheral blood, and the increasing use of reduced-intensity conditioning (RIC), renders feasible an allogeneic transplant to almost all patients with acute leukemia up to 70 years of age. Autologous stem cell transplantation (ASCT) for consolidation of complete remission (CR), however, offers in some circumstances an alternative option. Although associated with a higher relapse rate, autologous transplant benefits from a lower non-relapse mortality, the absence of graft-versus-host disease (GVHD), and a better quality of life for long-term survivors. The recent use of intravenous busulfan (IVBU) with high-dose melphalan, better monitoring of minimal residual disease (MRD), and maintenance therapy post autografting bring new interest. Few retrospective studies compared the outcome following alternative donor versus autologous transplants for remission consolidation. Genoidentical and phenoidentical allogeneic stem cell transplantations are undisputed gold standards, but there are no data showing the superiority of alternative allogeneic donor over autologous transplantation, at the time of undetectable MRD, in patients with good- and intermediate-1 risk acute myelocytic leukemia (AML) in first complete remission (CR1), acute promyelocytic leukemia in second complete remission (CR2), and Philadelphia chromosome-positive (Ph(+)) acute lymphocytic leukemia (ALL).

    Health information technology (HIT) has great potential for increasing patient engagement. Pediatric hematopoietic cell transplantation (HCT) is a setting ripe for using HIT but in which little research exists. "BMT Roadmap" is a web-based application that integrates patient-specific information and includes several domains: laboratory results, medications, clinical trial details, photos of the healthcare team, trajectory of transplant process, and discharge checklist. BMT Roadmap was provided to 10 caregivers of patients undergoing first-time HCT. Research assistants performed weekly qualitative interviews throughout the patient's hospitalization and at discharge and day 100 to assess the impact of BMT Roadmap. Rigorous thematic analysis revealed 5 recurrent themes: emotional impact of the HCT process itself; critical importance of communication among patients, caregivers, and healthcare providers; ways in which BMT Roadmap was helpful during inpatient setting; suggestions for improving BMT Roadmap; and other strategies for organization and management of complex healthcare needs that could be incorporated into BMT Roadmap. Caregivers found the tool useful and easy to use, leading them to want even greater access to information. BMT Roadmap was feasible, with no disruption to inpatient care. Although this initial study is limited by the small sample size and single-institution experience, these initial findings are encouraging and support further investigation.

    There are few data available regarding the prevalence of infection in multiple myeloma (MM patients in conjunction with newer generations of immunomodulatory drugs (thalidomide, bortezomib, lenalidomide or post autologous stem cell transplantation.  We retrospectively analyzed 47 patients with MM from March 2006 to June 2009 at our institution. All patients received thalidomide and steroid therapy for at least 6 months. Nine patients received bortezomib and 11 lenalidomide subsequently to thalidomide, because of disease progression and 22 patients underwent autologous stem cell transplantation.   The median age was 64 years (range 37-86, with a female–to-male ratio of 18:29. The median residual-serum IgG-level at time of infection was 3.2 g/L, IgA 0.3 g/L and IgM 0.2 g/L. Most patients suffered from recurrent moderate to severe infections. All patients except 3 received intravenous immunoglobulin (IVIG therapy with a significant decline of the rate of infection thereafter. Our analysis shows that IVIG appears to be an effective strategy to prevent infection in MM patients. Further studies to confirm these findings are warranted.

    Reduced-intensity conditioning (RIC) regimens for allogeneic stem cell transplant (allo-SCT) have used alemtuzumab to abrogate the risk of graft-versus-host disease (GVHD). Thirty-eight patients with advanced lymphoma underwent a prospective phase II study of melphalan, fludarabine and alemtuzumab containing RIC allo-SCT from 20 matched related and 18 unrelated donors with cyclosporine-A as GVHD prophylaxis. The cumulative incidence of grade II-IV acute GVHD at 3 months was 10.5% and three evaluable patients experienced chronic GVHD. Progression-free (PFS) and overall (OS) survival at 5 years was 25% (95% confidence interval [CI]: 13-40%) and 44% (95% CI: 28-59%), respectively. Previous high-dose therapy and autologous stem cell transplant (HDT-ASCT) and elevated lactate dehydrogenase (LDH) at the time of allo-SCT resulted in inferior OS. Within this cohort of patients with high-risk lymphoma, alemtuzumab containing RIC resulted in a low risk of GVHD and a high incidence of progression of disease, especially in those with poor-risk features defined by elevated LDH pre-allo-SCT and previous HDT-ASCT.

    Full Text Available INTRODUCTION: Patients undergoing hematopoietic stem cell transplantation receive high doses of chemotherapy and radiotherapy, which cause severe immunosuppression.OBJECTIVE: To report an oral disease management protocol before and after hematopoietic stem cell transplantation.METHODS: A prospective study was carried out with 65 patients aged > 18 years, with hematological diseases, who were allocated into two groups: A (allogeneic transplant, 34 patients; B (autologous transplant, 31 patients. A total of three dental status assessments were performed: in the pre-transplantation period (moment 1, one week after stem cell infusion (moment 2, and 100 days after transplantation (moment 3. In each moment, oral changes were assigned scores and classified as mild, moderate, and severe risks.RESULTS: The most frequent pathological conditions were gingivitis, pericoronitis in the third molar region, and ulcers at the third moment assessments. However, at moments 2 and 3, the most common disease was mucositis associated with toxicity from the drugs used in the immunosuppression.CONCLUSION: Mucositis accounted for the increased score and potential risk of clinical complications. Gingivitis, ulcers, and pericoronitis were other changes identified as potential risk factors for clinical complications.

Materials and Methods: The study adopted a descriptive design. The study sample comprised of 66 hematopoietic stem cell transplant patients. The study was conducted in Istanbul. Data were collected using Patient Information Form and Memorial Symptom Assessment Scale (MSAS. Results: The frequency of psychological symptoms in hematopoietic stem cell transplant patients after discharge period (PSYCH subscale score 2.11 (standard deviation (SD = 0.69, range: 0.93-3.80 was higher in hematopoietic stem cell transplant patients than frequency of physical symptoms (PHYS subscale score: 1.59 (SD = 0.49, range: 1.00-3.38. Symptom distress caused by psychological and physical symptoms were at moderate level (Mean = 1.91, SD = 0.60, range: 0.95-3.63 and most distressing symptoms were problems with sexual interest or activity, difficulty sleeping, and diarrhea. Patients who did not have an additional chronic disease obtained higher MSAS scores. University graduates obtained higher Global Distress Index (GDI subscale and total MSAS scores with comparison to primary school graduates. Total MSAS, MSAS-PHYS subscale, and MSAS-PSYCH subscale scores were higher in patients with low level of income (P < 0.05. The patients (98.5% reported to receive education about symptom management after hospital discharge. Conclusions: Hematopoietic stem cell transplant patients continue to experience many distressing physical or psychological symptoms after discharge and need to be supported and educated for the symptom management.

    Belinda Pinto Simões

    Full Text Available SUMMARY Sickle-cell diseases are the most common inherited hemoglobinopathies worldwide. Improvement in survival has been seen in the last decades with the introduction of careful screening and prevention of complications and the introduction of hydroxyurea. Stem-cell transplantation is currently the only curative option for these patients and has been indicated for patients with neurological events, repeated vaso-occlusive crisis, any organ damage or presence of red blood cell antibodies. Related bone-marrow or cord-blood transplant has shown an overall survival of more than 90% with a disease-free survival of 90% in 1,000 patients transplanted in the last decades. The use of unrelated donors unfortunately has not shown the same good results, but better typing methods and improved support may improve the outcome with this source of stem cells in the future. In Brazil, only recently stem cell transplant from related donors has been included in the procedures performed in the public health system. The use of related bone marrow or cord blood and a myeloablative conditioning regimen are considered standard of care for patients with sickle-cell diseases. Transplants with non-myeloablative regimens, unrelated donors or haploidentical donors should be performed only in controlled clinical trials.

    Treatment of primary central nervous system lymphoma (PCNSL) improved in recent years. However, the high neurotoxicity and low survival rates associated with this condition remain unresolved. We report 13 consecutive patients with PCNSL for whom upfront melphalan, cyclophosphamide, etoposide, and dexamethasone (known as LEED) followed by autologous stem-cell transplantation (ASCT) was planned at the Anjo Kosei Hospital. All patients were pathologically diagnosed with diffuse large B-cell lymphoma and were negative for human immunodeficiency virus. All patients were to receive three cycles of high-dose methotrexate-based induction chemotherapy, two cycles of high-dose AraC-based chemotherapy, and LEED followed by ASCT. All 13 patients achieved a partial response, and the 3-year overall survival (OS) rate was 76.2 %. Seven of the 13 patients were alive at the last follow-up, without any adverse events, including neurotoxicity. Six of the 13 (46.2 %) patients underwent ASCT and the 3-year OS rate was 80.0 %. Although this study included only a limited number of patients, these preliminary signs of efficacy and tolerability merit further consideration. To make further improvements in survival, the rate of patients undergoing ASCT should be increased. Other prospective studies involving greater numbers of patients are required to confirm these findings.

    AIM: To evaluate safety and feasibility of autologous bone marrow-enriched CD34+ hematopoietic stem cell Tx through the hepatic artery in patients with decompensated cirrhosis.METHODS: Four patients with decompensated cirrhosis were included. Approximately 200 mL of the bone marrow of the patients was aspirated, and CD34+ stem cells were selected. Between 3 to 10 million CD34+ cells were isolated. The cells were slowly infused through the hepatic artery of the patients.RESULTS: Patient 1 showed marginal improvement in serum albumin and no significant changes in other test results. In patient 2 prothrombin time was decreased;however, her total bilirubin, serum creatinine, and Model of End-Stage Liver Disease (MELD) score worsened at the end of follow up. In patient 3 there was improvement in serum albumin, porthrombin time (PT), and MELD score. Patient 4 developed radiocontrast nephropathy after the procedure, and progressed to type 1 hepatorenal syndrome and died of liver failure a few days later. Because of the major side effects seen in the last patient, the trial was prematurely stopped.CONCLUSION: Infusion of CD34+ stem cells through the hepatic artery is not safe in decompensated cirrhosis.Radiocontrast nephropathy and hepatorenal syndrome could be major side effects. However, this study does not preclude infusion of CD34+ stem cells through other routes.

As the number of transplants increases and the survival rate improves, long-term complications are important to recognize and treat to maintain quality of life. Sexual dysfunction is a commonly described but relatively often underestimated complication after HSCT. Conditioning regimens, generalized or genital graft-versus-host disease, medications, and car...

    Noninfectious pulmonary syndromes (NIPS) frequently complicate allogeneic stem cell transplantation (allo-SCT). The most common and serious is the bronchiolitis obliterans syndrome, characterized by irreversible fixed airflow obstruction, impaired quality of life, and a high mortality. Treatment for established symptomatic disease is relatively ineffective. We therefore sought to identify potential predictive factors for development of NIPS, which may identify patients at risk in whom earlier intervention may be of benefit. Spirometry and diffusing capacity for carbon monoxide were performed before allo-SCT, day 100, and 1 year after allo-SCT. We retrospectively analyzed spirometry in consecutive patients having allo-SCT from 2004 to 2010, along with computed tomography and bronchoalveolar lavage results to identify cases of NIPS. Cases of bronchiolitis obliterans syndrome were defined as per current National Institutes of Health consensus guidelines. Spirometry results and baseline variables were compared between patients with and without NIPS to identify early predictors and risk factors for NIPS. Of 235 assessable patients, 23 (9.8%) developed NIPS. Median time of onset was day 367 (interquartile range [IQR], 144 to 544 days). Changes in forced expiratory volume in 1 second (ΔFEV1.0) was the best predictor of later NIPS development. Median ΔFEV1.0 from pretransplant to day 100 in patients later developing NIPS was -12% (IQR, -25% to -1%) versus -1% (IQR, -7% to +6%) in unaffected patients, P = .002. From pretransplant to 1 year, ΔFEV1.0 was -19% (IQR, -37% to -6%) versus -3% (IQR, -10% to +4%) in patients later developing NIPS and unaffected patients, respectively, P Spirometry is a potentially useful screening test for identification of presymptomatic NIPS. We recommend 3-monthly spirometry surveillance for up to 2 years post-transplant. Our findings require prospective validation to identify patients in whom earlier intervention may potentially modify the

    The prognosis of human immunodeficiency virus (HIV) infection has improved in recent years with the introduction of antiretroviral treatment. While the frequency of AIDS-defining events has decreased as a cause of death, mortality from non-AIDS-related events including end-stage renal diseases has increased. The etiology of chronic kidney disease is multifactorial: immune-mediated glomerulonephritis, HIV-associated nephropathy, thrombotic microangiopathies, and so on. HIV infection is no longer a contraindication to transplantation and is becoming standard therapy in most developed countries. The HIV criteria used to select patients for renal transplantation are similar in Europe and North America. Current criteria state that prior opportunistic infections are not a strict exclusion criterion, but patients must have a CD4+ count above 200 cells/mm(3) and a HIV-1 RNA viral load suppressible with treatment. In recent years, more than 200 renal transplants have been performed in HIV-infected patients worldwide, and mid-term patient and graft survival rates have been similar to that of HIV-negative patients. The main issues in post-transplant period are pharmacokinetic interactions between antiretrovirals and immunosuppressants, a high rate of acute rejection, the management of hepatitis C virus coinfection, and the high cardiovascular risk after transplantation. More studies are needed to determine the most appropriate antiretroviral and immunosuppressive regimens and the long-term outcome of HIV infection and kidney graft.

    Full Text Available BACKGROUND AND OBJECTIVES: Regimens incorporating hematopoietic stem cell transplantation (HSCT have become widely utilized in disease treatments, particularly for cancer. These complex treatment programs also expose patients to central nervous system (CNS toxicities from chemotherapy, irradiation, infection, metabolic effects and immunosuppression. METHODS: Relevant recent medical literature from Medline and bibliographies in pertinent publications are reviewed with a focus on those cases and studies pertaining to neuropsychiatric effects of HSCT. RESULTS: High rates of neuropsychiatric sequelae occur on a continuum from acute to chronic. Adverse outcomes include focal CNS deficits and severe global manifestations such as seizures, encephalopathy and delirium. More graduated effects on cognition, energy and mood are frequently seen, impacting patient function. CONCLUSIONS: Additional research on neuropsychiatric outcomes and treatment interventions is needed in the HSCT setting. Risks for neuropsychiatric deficits should be part of an ongoing informed consent discussion among treating physicians, patients and families.

    Stem cell transplantation affects patient׳s vulnerability to infections due to immunological changes related to chemotherapy. Multiple myeloma is characterized by susceptibility to infections, and IL-6 and TNF-α increased levels affect immune response (IR). Polymorphisms in promoter region of cytokine genes may alter expression levels and affect IR. We performed interaction analysis of IL-6 (-174G/C) and TNF-α (-308G/A) polymorphisms with infection susceptibility in 148 patients classified accordingly to infection status and found an interaction when compared groups with and without bacteremia (p=0.0380). The interaction may be more important than single effects for the IR associated with the infection susceptibility in ASCT.

    Teresa L Field

    2010-07-01

    Full Text Available Allogeneic hematopoietic cell transplantation (HCT is the only curative treatment for patients with myelodysplastic syndromes (MDS.  Most patients with MDS are older than 60 years and age-associated morbidities limit the patients’ options for curative transplant therapy.  Since the development of conditioning regimens with reduced toxicity, the age limitations for HCT have waned for those patients with good performance status. This review will discuss the role of HCT for MDS based on prognostic features, the optimal timing of HCT, and outcomes based on patient age.

    The distribution and functional characteristics of in vitro bone marrow (BM) endothelial colonies (CFU-En) were studied in 70 non-Hodgkin's lymphoma (NHL) patients in different phases of the disease to explore the association between CFU-En growth and angiogenesis, and between the number of CFU-En and the presence of hematopoietic and mesenchymal progenitor cells. The mean number of CFU-En/10(6) BM mononuclear cells seen in remission patients was significantly higher than that seen in newly diagnosed patients (P=0.04), and in normal subjects (P=0.008). Patients with low-grade NHL in remission displayed a higher CFU-En value compared with high-grade NHL (P=0.04). In the autograft group (40 patients), a significant reduction of CFU-En number was detected in the first 4-6 months after transplantation. In remission patients, the CFU-En number positively correlated with the incidence of BM colony-forming unit granulocyte-macrophage (CFU-GM) (P=0.013) and CFU-multilineage (CFU-GEMM) hematopoietic colonies (P=0.044). These in vitro data show that CFU-En numbers increase following standard-dose chemotherapy, thus providing a rationale for further investigating the effects of different cytostatic drugs on BM endothelial cells growth and function.

  18. [Kidney transplant in patients with HIV infection].

    2012-01-01

    Until recently, human immunodeficiency virus (HIV) infection was an absolute contraindication to solid organ transplantation because it was feared that the anti-rejection therapy could result in accelerated HIV disease. At the end of the 1990s it became clear that HIV infection, once deemed a fatal disease, could be effectively turned into a chronic condition by the use of highly active antiretroviral therapy. Since then, the mortality rate from opportunistic infections has decreased dramatically, while liver and renal insufficiency have become the major causes of morbidity and mortality in these patients in the long term. A growing number of HIV patients develop end-stage renal disease secondary to immune-mediated glomerulonephritis, HIV-associated nephropathy, nephrotoxic effects induced by antiretroviral medication, or diabetic and vascular nephropathy, and therefore need maintenance dialysis. For this reason we have to reconsider kidney transplant as a possible treatment option. During the last decade, the results of many studies have shown that transplantation can be safe and effective as long as the HIV infection is effectively controlled by antiretroviral therapy. The short- and medium-term patient and graft survival rates in HIV-positive transplant recipients are comparable with those of the overall transplant population, but the incidence of acute rejection episodes is higher. The main clinical problem in the management of HIV-positive transplant recipients originates from the interference between immunosuppressive regimens and antiretroviral drugs. Thus, a close collaboration between infectious disease specialists and nephrologists is mandatory in order to optimize transplantation programs in these patients.

    2011-08-10

    Abstract Background Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disorder that results in the accumulation of glycosaminoglycans causing progressive multi-organ dysfunction. Its clinical spectrum is very broad and varies from the severe Hurler phenotype (MPS I-H) which is characterized by early and progressive central nervous system (CNS) involvement to the attenuated Scheie phenotype (MPS I-S) with no CNS involvement. Indication, optimal timing, safety and efficacy of the two available treatment options for MPS I, enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT), are subject to continuing debate. A European consensus procedure was organized to reach consensus about the use of these two treatment strategies. Methods A panel of specialists, including 8 specialists for metabolic disorders and 7 bone marrow transplant physicians, all with acknowledged expertise in MPS I, participated in a modified Delphi process to develop consensus-based statements on MPS I treatment. Fifteen MPS I case histories were used to initiate the discussion and to anchor decisions around either treatment mode. Before and at the meeting all experts gave their opinion on the cases (YES\\/NO transplantation) and reasons for their decisions were collected. A set of draft statements on MPS I treatment options composed by a planning committee were discussed and revised during the meeting until full consensus. Results Full consensus was reached on several important issues, including the following: 1) The preferred treatment for patients with MPS I-H diagnosed before age 2.5 yrs is HSCT; 2) In individual patients with an intermediate phenotype HSCT may be considered if there is a suitable donor. However, there are no data on efficacy of HSCT in patients with this phenotype; 3) All MPS I patients including those who have not been transplanted or whose graft has failed may benefit significantly from ERT; 4) ERT should be started at diagnosis and may be

  1. Implication of thymoglobulin in kidney transplant patients: review article

    2015-11-01

    Full Text Available Thymoglobulin is a purified polyclonal immunoglobulin that has been used widely over the last decades in the prevention and treatment of rejection following renal transplantation. This immunoglobulin works against human thymocytes. Since thymoglobulin does not contain the nephrotoxic properties therefore it can be used in induction therapy especially in patients with higher risk of graft rejection such as patients who receive graft from cadavers. Recent research showed also its beneficial role in cross-match-positive transplantation, a role that is mediated through conjunction with inhibitors of terminal complement activation. This immunoglobulin has also been used for treatment of rejection following renal transplantation. Thymoglobulin can have various effects on various Immune system cells including T cells, B cells and also plasma cells. Thymoglobulin also affects the Tcell surface antigens, natural killer-cell antigens, B cell antigens, plasma cell antigens, adhesion molecules and chemokine receptors. Diverse effects of thymoglobulin on the immune system includes: T cell depletion, induce apoptosis in B cell lineage and interference with dendritic cell functional properties. Thymoglobulin can cause acute complications, delayed complications as well as infectious complications. Acute reaction events includes: anaphylaxis, fever, chills, dyspnea, nausea, vomiting and diarrhea. Thymoglobulin also induces cytokine release syndrome manifested by high grade fevers and chills and treated by steroid therapy. Delayed reactions events usually present as serum sickness and infections. Infectious complications are more important and include cytomegalovirus (CMV infection, sepsis, candidiasis, herpes simplex and urinary infections. Thymoglobulin can also induce cytokine release syndrome. It has been thought that thymoglobulin increases the risk of post-transplant lymphoproliferative disorder (PTLD, however, debate still exists whether such an

    Bloodstream infections (BSI) are still important complications after allogeneic hematopoietic stem cell transplantation (allo-SCT). Patients who are receiving corticosteroid therapy can develop BSI without fever. The utility of surveillance blood cultures in these situations is controversial. We retrospectively analyzed 74 patients who received a corticosteroid consisting of ≥.5 mg/kg prednisolone or equivalent after allo-SCT. In principle, we performed surveillance blood culture weekly for these patients. Sixteen patients (21.6%) developed definite BSI. In a multivariate analysis, a myeloablative conditioning regimen, high-risk disease status at allo-SCT, and the presence of a central venous catheter at the initiation of corticosteroid therapy were identified as independent significant risk factors for the development of definite BSI. At the first definite BSI episode, 7 patients (46.7%) were afebrile and diagnosed by surveillance blood culture. However, 6 of these 7 afebrile patients showed various signs that could be attributed to infection at the time of positive blood culture. In conclusion, patients receiving corticosteroid therapy after allo-SCT frequently develop afebrile BSI. Although surveillance blood culture might be beneficial in these situations, it also seems important to not miss the signs of BSI, even when patients are afebrile.

    Cidofovir is a deoxycytidine monophosphate analog with broad spectrum activity against various deoxyribonucleic acid viruses. Cidofovir is marketed as an injectable for intravenous use; however, there is a topical cidofovir formulation utilized for viral dermatologic infections. Here, we present a case of a successful clearance of a perianal acyclovir resistant and foscarnet refractory herpes simplex virus (HSV1) ulcer in a 34 year-old woman who had undergone allogeneic hematopoietic stem cell transplantation. After 1 week of therapy with cidofovir gel, the patient's ulcer was clinically improved, and the lesion was negative for herpes simplex virus transcripts by real-time polymerase chain reaction testing. The wound remained herpes simplex virus negative by real-time polymerase chain reaction on repeat testing 1 week later. Based on this and other reports in HIV/AIDS patients, we believe that cidofovir gel has utility in the management of cutaneous, acyclovir-resistant HSV infections.

    Full Text Available Although bone marrow transplantation (BMT from an HLA identical sibling is considered as treatment of choice in pediatric patients with severe aplastic anemia (SAA, a significant number of them experience graft failure (GF after BMT. We report a case of an 8-year-old male patient with SAA who presented with a complicated posttransplant course due to parvovirus B19 infection and GF. A subsequent attempt to support the graft by antithymocyte globulin (ATG and a peripheral stem cell boost resulted in transitory autologous recovery of hematopoiesis followed by mixed chimerism, supported by donor lymphocyte infusions (DLIs and finally graft rejection with relapse of SAA. Permanent complete chimerism was achieved by a second BMT. Dynamics of graft function, measured by a single nucleotide polymorphism (SNPs analysis, are discussed.

    Full Text Available Background: Thalassemic patients undergoing Hematopoietic Stem Cell Transplantation (HSCT are faced with cumulative high level of oxidative stress and depletion of critical antioxidants. Administration of antioxidants, is promising towards minimizing oxidative damage in both thalassemic and HSCT patients.Method: This was a prospective cross-sectional observational study. Patients as a part of institutional protocol were received Vitamin C (Vit C (all the patients received oral Vit C; 200 mg and 400 mg Vit C, if they were less or more than 20 kg respectively plus 10 mg/kg/day intravenous infusion of Vit C.We measured plasma Vit C and total antioxidant (TAs levels at four different time points; baseline, transplantation day (0, day +7 and day +14. We calculated mean and standard error for plasma levels of Vit C and TAs.Results: Fifthy patients enrolled in this study (mean age 7.97± 3.53. In all four time points, means of Vit C and TAs serum levels were under their reference values and their highest means were belong to baseline. Serum TAs and Vit C both depleted significantly from baseline to day 0 (P: 0.00 for both variables, then increased up to day +7 and it keeps rising till day +14 (P: 0.00 from day0 to day +7 and +14 for both variables. These changes were significant through the measurement time. There is also a significant correlation between baseline Vit C and baseline TAs (P: 0.11. This means the higher level of Vit C is correlated with higher level of TAs and vice versa.Conclusion: We did not observe any beneficial effects of administering Vit C in thalassemic patients undergoing HSCT in order to increase or prevent depletion of Vit C and TAs serum levels. This could be resolved by further investigations carrying out higher doses or longer duration and having a control group.

    Full Text Available Objective: It was aimed to identify skin findings those were seen in patients who undergone renal transplantation. Methods: Patients who have been followed in Erciyes University Nephrology Hospital renal transplantation outpatient clinic were included in the study. They were evaluated for dermatologic findings during routine controls. Age, gender, transplantation date, identity of organ donor, history of medications, dermatological history and dermatological findings during examination were recorded. Biopsy was performed when needed. Results: In total 94 patients, 25 female (26.6% and 69 male (73.4%, were recruited to the study. Mean age was 36±10 years. The most frequent skin finding was drug-related acne (n=20. Most common infectious disease was verruca (n=17. There were viral disease other than verruca such as herpes zoster (n=3, superficial mycosis such as onychomycosis (n=5, tinea versicolor, tinea pedis and bacterial skin disease (n=2, and paronychia (n=1 and pre-malign lesions such as actinic cheilitis and bowenoid papulosis. Besides these, stria (n=3, kserosis (n=2, cornu cutaneum, café-au-lait spots, sebaceous hyperplasia and seborrheic dermatitis, skin tag, hypertrichosis, unguis incarinatus and calcinosis were other skin findings those were seen. No malign skin lesion was observed in any of patients. Conclusion: Miscellaneous skin lesions should develop in patients those undergone renal transplantation due to long-term utilization of various immunosuppressive drugs.

Cardiac resynchronization therapy (CRT) has also shown a beneficial effect in patients with heart failure (HF) and electrical/mechanical dyssynchrony. However, the relative contribution of BMMC and CRT in patients with ischemic HF and electromechanical dyssynchrony has never been investigated. The aim of this study was to evaluate the benefit of combining BMMC transplantation with CRT in patients with severe ischemic HF, left bundle branch block (LBBB), and mechanical dyssynchrony. Patients with ischemic HF, LVEF < 35%, LBBB, and mechanical dyssynchrony underwent intramyocardial transplantation of BMMC and CRTD system implantation. This randomized, single-blind, crossover study compared clinical and echocardiographic parameters during two follow-up periods: 6 months of active CRT (BMMC + CRTact) and 6 months of inactive CRT (BMMC + CRTinact). Physical performance was assessed by means of a 6-min walking test. Myocardial perfusion was evaluated by SPECT. Quality of Life (QoL) was assessed through the Minnesota Living with HF Questionnaire (MLwHFQ). Twenty-six patients (64 ± 7 years) were enrolled in the study. The distance covered by the patients during the 6-min walking test significantly increased in the BMMC + CRTinact phase (BMMC therapy only) in comparison with the baseline (269 ± 68 vs 206 ± 51; p = 0.007) and in the BMMC + CRTact phase (BMMC therapy + CRT) in comparison with the BMMC + CRTinact (378 ± 59 vs 269 ± 68; p < 0.001). The summed rest and stress score (SPECT) decreased significantly in the BMMC + CRTact and BMMC + CRTinact phases in comparison with the baseline (p ≤ 0.03). Both phases showed equivalent myocardial perfusion in the segments into which BMMC had been injected. QoL score was significantly lower in the BMMC

    Breast cancer carrying BRCA mutation may be highly sensitive to DNA-damaging agents. We hypothesized a better outcome for BRCA-mutated (BRCA(mut)) metastatic breast cancer (MBC) patients receiving high-dose chemotherapy and autologous hematopoietic stem cell transplantation (HDC AHSCT) versus unaffected BRCA (BRCA wild type; (BRCA(wt))) or patients without documented BRCA mutation (BRCA untested (BRCA(ut))). All female patients treated for MBC with AHSCT at Institut Paoli-Calmettes between 2003 and 2012 were included. BRCA(mut) and BRCA(wt) patients were identified from our institutional genetic database. Overall survival (OS) was the primary end point. A total of 235 patients were included. In all, 15 patients were BRCA(mut), 62 BRCA(wt) and 149 BRCA(ut). In multivariate analyses, the BRCA(mut) status was an independent prognostic factor for OS (hazard ratio (HR): 3.08, 95% confidence interval (CI): 1.10-8.64, P=0.0326) and PFS (HR: 2.52, 95% CI :1.29-4.91, P=0.0069). In this large series of MBC receiving HDC AHSCT, we report a highly favorable survival outcome in the subset of patients with documented germline BRCA mutations.

    Poor graft function (PGF), including early and late PGF, is a serious complication following allotransplant. We recently reported that bone marrow microenvironment abnormalities may occur in cases of late PGF. Whether these abnormalities occur in early PGF remains unknown. To answer this question, we performed a nested case-control study comparing cellular elements of the bone marrow microenvironment in 10 subjects with early PGF, 30 subjects with late PGF and 40 subjects without PGF. Bone marrow endosteal cells, perivascular cells and endothelial cells were analyzed by flow cytometry and by hematoxylin-eosin and immunohistochemical staining in situ. Subjects with early and late PGF had similar abnormalities in these cell types compared with transplant recipients without PGF. However, none of the aforementioned elements of the bone marrow microenvironment were significantly different between early and late PGF patients. Our data suggest that similar abnormalities in the bone marrow microenvironment may occur in early and late PGF post allotransplant. Cellular approaches, such as the administration of mesenchymal stem cells, promise to be beneficial therapeutic strategies in patients with early or late PGF.

    Hematopoietic stem cell transplantation (HSCT) plays a central role in patients with malignant and, increasingly, nonmalignant conditions. As the number of transplants increases and the survival rate improves, long-term complications are important to recognize and treat to maintain quality of life. Sexual dysfunction is a commonly described but relatively often underestimated complication after HSCT. Conditioning regimens, generalized or genital graft-versus-host disease, medications, and cardiovascular complications as well as psychosocial problems are known to contribute significantly to physical and psychological sexual dysfunction. Moreover, it is often a difficult topic for patients, their significant others, and health care providers to discuss. Early recognition and management of sexual dysfunction after HSCT can lead to improved quality of life and outcomes for patients and their partners. This review focuses on the risk factors for and treatment of sexual dysfunction after transplantation and provides guidance concerning how to approach and manage a patient with sexual dysfunction after HSCT.

    Stem cell based therapy was very attractive in decompensated liver cirrhosis currently. The possible mechanism might be due to its potential to help tissue regeneration with minimally invasive procedures. Here we report the case of a 44-year-old man, infected by hepatitis B virus (HBV) combined with hepatitis C virus (HCV) for longer than 10 years, who eventually developed decompensated liver cirrhosis. After being infused with mobilized peripheral blood stem cells, the patient showed signifi...

    We report the international experience in outcomes after related and unrelated hematopoietic transplantation for infantile osteopetrosis in 193 patients. Thirty-four percent of transplants used grafts from HLA-matched siblings, 13% from HLA-mismatched relatives, 12% from HLA-matched, and 41% from HLA-mismatched unrelated donors. The median age at transplantation was 12 months. Busulfan and cyclophosphamide was the most common conditioning regimen. Long-term survival was higher after HLA-matched sibling compared to alternative donor transplantation. There were no differences in survival after HLA-mismatched related, HLA-matched unrelated, or mismatched unrelated donor transplantation. The 5- and 10-year probabilities of survival were 62% and 62% after HLA-matched sibling and 42% and 39% after alternative donor transplantation (P = .01 and P = .002, respectively). Graft failure was the most common cause of death, accounting for 50% of deaths after HLA-matched sibling and 43% of deaths after alternative donor transplantation. The day-28 incidence of neutrophil recovery was 66% after HLA-matched sibling and 61% after alternative donor transplantation (P = .49). The median age of surviving patients is 7 years. Of evaluable surviving patients, 70% are visually impaired; 10% have impaired hearing and gross motor delay. Nevertheless, 65% reported performance scores of 90 or 100, and in 17%, a score of 80 at last contact. Most survivors >5 years are attending mainstream or specialized schools. Rates of veno-occlusive disease and interstitial pneumonitis were high at 20%. Though allogeneic transplantation results in long-term survival with acceptable social function, strategies to lower graft failure and hepatic and pulmonary toxicity are urgently needed.

    A record number of 40 829 hematopoietic stem cell transplantation (HSCT) in 36 469 patients (15 765 allogeneic (43%), 20 704 autologous (57%)) were reported by 656 centers in 47 countries to the 2014 survey. Trends include: continued growth in transplant activity, more so in Eastern European countries than in the west; a continued increase in the use of haploidentical family donors (by 25%) and slower growth for unrelated donor HSCT. The use of cord blood as a stem cell source has decreased again in 2014. Main indications for HSCT were leukemias: 11 853 (33%; 96% allogeneic); lymphoid neoplasias; 20 802 (57%; 11% allogeneic); solid tumors; 1458 (4%; 3% allogeneic) and non-malignant disorders; 2203 (6%; 88% allogeneic). Changes in transplant activity include more allogeneic HSCT for AML in CR1, myeloproliferative neoplasm (MPN) and aplastic anemia and decreasing use in CLL; and more autologous HSCT for plasma cell disorders and in particular for amyloidosis. In addition, data on numbers of teams doing alternative donor transplants, allogeneic after autologous HSCT, autologous cord blood transplants are presented.

    Fungal infection remains a major hurdle in solid organ transplantation. A variety of new antifungal agents have become available and new diagnostic tools are in development. This conference was convened to review current approaches to the prevention and treatment of fungal infection in transplantation. Among the keys to successful management of fungal infection are identification of patients at risk for infection (stratification), eradication or control of established infection in advance of transplantation, the demonstration of cure by radiologic and histopathologic means, and the use of surgical debridement, reduction in immune suppression, and fungicidal therapies whenever possible. The absence of sensitive diagnostic tools and standardization of antifungal susceptibility testing for the filamentous fungi are identified as major impediments to care in this area.

    Avascular necrosis of the femoral head (AVNFH) is a known complication after heart transplantation. In order to assess the efficacy and complications of cementless total hip arthroplasty (THA) in this population, the authors analysed 24 cementless THAs in 18 patients with advanced AVNFH (stage II affecting more than 15% of the articular surface, stage III and IV according to the Ficat-Arlet classification) after a heart transplant procedure. Average duration of follow-up was 35.4 months (range: 16 to 66). Pain and function scores (Harris Hip Score and WOMAC arthritis index) showed significant improvement from the preoperative levels. There was no evidence of component loosening, heart-related complications or infection following the THA. Cementless THA is a reasonable treatment option for advanced avascular necrosis of the femoral head following heart transplant procedures.

    Purpose To review the characteristics and evolution of the fungal spectrum, and the risk factors causing fungal infection, and to make progress in diagnosing fungal infection after organ transplantation.Data sources An English-language literature search (MEDLINE 1990-2000) and bibliographic review of textbooks and review articles.Study selection Twenty-three articles were selected from the literature that specifically addressed the stated purpose.Results Fungal infections in organ transplant patients were generally divided into two types: ① disseminated primary or reactivation infection with one of the geographically restricted systemic mycoses; ② opportunistic infection by fungal species that rarely cause invasive infection in normal hosts. The risk factors of fungal infection after a transplant can be evaluated and predicted according to the organ recipient ’s conditions before, during and after the transplant. Progress in early diagnostic methods during the past 10 years has mainly revolved around two aspects, culture and non-culture. Conclusions It is important to undertake a systemic evaluation on the condition of the organ recipient before, during and after a transplant; should any risk factor for fungal infection be suspected, diagnosis should be made as early as possible by employing mycological techniques including culture and non-culture methods.

    Immunosuppressed transplant recipients have increased risk for the development of basal cell carcinoma skin cancers. While oral vismodegib therapy has been successful in treating locally advanced basal cell tumors, few studies document its use and efficacy in organ transplant patients. In this immunocompromised population, topical imiquimod 5% cream has been shown to be an effective and well-tolerated option for superficial and nodular basal cell carcinomas. To the authors’ knowledge, no data documents the use of optical coherence tomography, a noninvasive imaging technique, to monitor progress of such combined therapies on in vivo skin. The authors report the successful treatment of an extensive basal cell carcinoma on the nose of an immunosuppressed 54-year-old Caucasian man with a history of kidney and pancreas transplantations. By combining continuous noninvasive lesion monitoring with vismodegib 150mg/d therapy and adjuvant imiquimod 5% topical cream, the patient showed complete disease clearance on clinical, optical coherence tomography, and histological evaluation. This report supports the feasibility and efficacy of nonsurgical treatment of basal cell lesions in complicated transplant patients and the need for individualized treatment plans. A noninvasive follow-up tool, especially during nonsurgical therapy, is of critical value to ensure the best possible treatment outcome for the patient. PMID:27672417

    A prospective pilot study was performed to evaluate the effect of reduced-intensity conditioning with busulphan (10 mg/kg), fludarabine (180 mg/qm) and anti-thymocyte globulin followed by allogeneic stem cell transplantation from related (n = 8) and unrelated donors (n = 13) in 21 patients with myelofibrosis. The median age of the patients was 53 years (range, 32-63). No primary graft failure occurred. The median time until leucocyte (>1.0 x 10(9)/l) and platelet (>20 x 10(9)/l) engraftment was 16 (range, 11-26) and 23 d (range, 9-139) respectively. Complete donor chimaerism on day 100 was seen in 20 patients (95%). Acute graft-versus-host disease (GvHD) grades II-IV and III/IV occurred in 48% and 19% of cases and 55% of the patients had chronic GvHD. Treatment-related mortality was 0% at day 100 and 16% [95% confidence interval (CI): 0-32%] at 1 year. Haematological response was seen in 100% and complete histopathological remission was observed in 75% of the patients and 25% of the patients showed partial histopathological remission with a continuing decline in the grade of fibrosis. After a median follow-up of 22 months (range, 4-59), the 3-year estimated overall and disease-free survival was 84% (95% CI: 67-100%).

    To describe the pulmonary complications following hematopoietic stem cell transplantation (HSCT) that can present with a 'crazy-paving' pattern in high-resolution CT scans. Retrospective review of medical records from 2,537 patients who underwent HSCT. The 'crazy-paving' pattern consists of interlobular and intralobular septal thickening superimposed on an area of ground-glass attenuation on high-resolution CT scans. The CT scans were retrospectively reviewed by two radiologists, who reached final decisions by consensus. We identified 10 cases (2.02%), seven male and three female, with pulmonary complications following HSCT that presented with the 'crazy-paving' pattern. Seven (70%) patients had infectious pneumonia (adenovirus, herpes simplex, influenza virus, cytomegalovirus, respiratory syncytial virus, and toxoplasmosis), and three patients presented with non-infectious complications (idiopathic pneumonia syndrome and acute pulmonary edema). The 'crazy-paving' pattern was bilateral in all cases, with diffuse distribution in nine patients (90%), predominantly in the middle and inferior lung regions in seven patients (70%), and involving the anterior and posterior regions of the lungs in nine patients (90%). The 'crazy-paving' pattern is rare in HSCT recipients with pulmonary complications and is associated with infectious complications more commonly than non-infectious conditions.

    Bloodstream infection (BSI) is a significant complication following allogeneic hematopoietic stem cell transplantation (allo-SCT). Corticosteroids mask inflammatory responses, delaying the initiation of antibiotics. We reviewed medical records of 69 allo-SCT patients who had been on >0.5 mg/kg prednisolone to investigate the efficacy of weekly surveillance blood cultures. A total of 36 patients (52%) had positive cultures, 25 definitive BSI and 11 probable BSI. Pathogens in definitive BSI were Staphylococcus epidermidis (n=7), S. aureus (n=4), Entrococcus faecalis (n=3), Pseudomonas aeruginosa (n=5), Acenitobacter lwoffii (n=4), and others (n=10). The median interval from the initiation of corticosteroids to the first positive cultures was 24 days (range, 1-70). At the first positive cultures, 15 patients with definitive BSI were afebrile. Four of them remained afebrile throughout the period of positive surveillance cultures. Patients with afebrile BSI tended to be older (P=0.063), and had in-dwelling central venous catheters less frequently than febrile patients (P<0.0001). Bloodstream pathogens were directly responsible for death in two patients with afebrile BSI. This study demonstrates that cortisosteroid frequently masks inflammatory reactions in allo-SCT recipients given conrticosteroids, and that surveillance blood culture is only diagnostic clue for 'occult' BSI.

    Background High-dose chemotherapy followed by autologous stem cell transplantation is the standard treatment for relapsed and/or refractory Hodgkin’s lymphoma although half of patients relapse after transplantation. Predictive factors, such as relapse within 12 months, Ann-Arbor stage at relapse, and relapse in previously irradiated fields are classically used to identify patients with poor outcome. Recently, 18-fluorodeoxyglucose positron emission tomography has emerged as a new method for providing information to predict outcome. The aim of this study was to confirm the predictive value of positron emission tomography status after salvage therapy and to compare single versus tandem autologous stem cell transplantation in patients with relapsed and/or refractory Hodgkin’s lymphoma. Design and Methods We report a series of 111 consecutive patients with treatment-sensitive relapsed and/or treatment-refractory Hodgkin’s lymphoma who achieved complete (positron emission tomography-negative group) or partial remission (positron emission tomography-positive group) at positron emission tomography evaluation after salvage chemotherapy and who underwent single or tandem autologous stem cell transplantation. Results Five-year overall and progression-free survival rates were 81% and 64%, respectively. There were significant differences in 5-year progression-free survival (79% versus 23%; P<0.001) and 5-year overall survival (90% versus 55%, P=0.001) between the positron emission tomography-negative and -positive groups, respectively. A complete response, as determined by positron emission tomography evaluation, after salvage therapy predicted significantly better 5-year overall survival rates in both intermediate (91% versus 50%; P=0.029) and unfavorable (89% versus 58%; P=0.026) risk subgroup analyses. In the positron emission tomography-positive subgroup, tandem transplantation improved 5-year progression-free survival from 0% (in the single transplantation group) to

    The characteristics of relapse following reduced-intensity stem-cell transplantation (RIST) remain to be clarified. We reviewed the medical records of 19 patients with acute leukaemia [acute myeloid leukaemia (AML), 16; acute lymphoblastic leukaemia (ALL), 3] who relapsed after RIST from related donors using purine-analogue-based regimens. Their median age was 55 years (range, 29-65 years). Median interval between RIST and relapse was 4.9 months (range, 1.8-24.9 months). Three chose not to receive interventions. The remaining 16 patients received withdrawal of immunosuppression (n = 3), chemotherapy (n = 2), donor lymphocyte infusion (n = 10) and second transplantation (n = 7), alone (n = 9) or in combination (n = 7). Four are alive with a median follow-up of 27.6 months (range, 16.0-28.9 months); three in remission and one in relapse. The 2-year overall survival after relapse was 28.9%. Causes of death in 15 patients included progressive disease (n = 7), graft-versus-host disease (n = 5) and infections (n = 3). Cumulative incidences of relapse-related and non-relapse-related deaths at 2 years after relapse were 37% and 32% respectively. Two prognostic factors were identified on univariate analysis: age [P = 0.017; hazard ratio (HR), 1.16; 95% confidence interval (CI), 1.03-1.32], and ALL as underlying disease (P = 0.011; HR, 10.4; 95% CI, 1.73-62.4). Some AML patients who relapse after RIST achieve durable remission with allogeneic immunotherapy-based interventions; however they carry a significant risk of non-relapse mortality.

    Full Text Available The overall objective of cell transplantation is to repopulate postinfarction scar with contractile cells, thus improving systolic function, and to prevent or to regress the remodeling process. Direct implantation of isolated myoblasts, cardiomyocytes, and bone-marrow-derived cells has shown prospect for improved cardiac performance in several animal models and patients suffering from heart failure. However, direct implantation of cultured cells can lead to major cell loss by leakage and cell death, inappropriate integration and proliferation, and cardiac arrhythmia. To resolve these problems an approach using 3-dimensional tissue-engineered cell constructs has been investigated. Cell engineering technology has enabled scaffold-free sheet development including generation of communication between cell graft and host tissue, creation of organized microvascular network, and relatively long-term survival after in vivo transplantation.

    Objective Fludarabine plus melphalan (FM) and fludarabine plus busulfan (FB) are two major conditioning regimens for allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods We retrospectively analyzed patients who underwent allo-HSCT after a conditioning regimen consisting of FM or FB with/without total body irradiation for hematological malignancies between 2005 and 2014. Results There were 41 patients who met the criteria. The median follow-up time for the survivors was 3 years. Thirty-two patients received allo-HSCT after the FM regimen and nine patients received allo-HSCT after the FB regimen. Patients who received FB were older than those who received FM (p=0.041). There was no significant difference in the 3-year overall survival between patients who had received FB and those who had received FM (29.6% vs. 56.5%, p=0.267). The 3-year cumulative incidence of relapse was significantly higher in patients who had received FB than that in patients who had received FM (66.7% vs. 17.8%, p=0.004), and FB was an independent prognostic factor for relapse by a multivariate analysis (hazard ratio, 9.8; 95% confidential interval, 2.5-39.3; p=0.001). When we restricted the evaluation to patients with acute myeloid leukemia and myelodysplastic syndrome, the 3-year cumulative incidence of relapse was also significantly higher in patients who had received FB than that in patients who had received FM (75.0% vs. 16.1%, p=0.004). Conclusion The results suggest that FM may provide better disease control than FB.

    The value of pre-transplant factors for predicting the development of cardiac complications after transplantation has been inconsistent among studies. We analyzed the impact of pre-transplant factors on the incidence of severe cardiac complications in 164 hematopoietic stem cell transplant recipients. We identified eight patients (4.8%) who experienced grade III or IV cardiac complications according to the Bearman criteria. Seven died of cardiac causes a median of 3 days after the onset of cardiac complications. On univariate analysis, both the cumulative dose of anthracyclines and the use of anthracyclines within 60 days before transplantation affected the incidence of severe cardiac complications (P=0.0091 and 0.011). The dissociation of heart rate and body temperature, which reflects "relative tachycardia", was also associated with a higher incidence of cardiac complications (P=0.024). None of the variables obtained by electrocardiography or echocardiography were useful for predicting cardiac complications after transplantation, although the statistical power might not be sufficient to detect the usefulness of ejection fraction. On a multivariate analysis, the cumulative dose of anthracyclines was the only independent significant risk factor for severe cardiac complications. We conclude that the cumulative dose of anthracyclines is the most potent predictor of cardiac complications and the administration of anthracyclines should be avoided within two months before transplantation.

    Minimal residual disease (MRD) of 30 adult AML patients was monitored by multiparameter flow cytometry (MFC) and WT1 expression before and after allogeneic stem cell transplantation (allo-SCT). Diagnostic performance of pre-transplant MRD measured by MFC was higher than that obtained by WT1 expression. Comparable results were displayed at day +30 post-transplant, while better values by WT1 compared to MFC were found at day +90. Positive MRD by MFC predicted a shorter disease free survival (DFS) before and 1 month after transplant (p=0.006 and p=0.005), while only high WT1 levels at 1 month from the transplant significantly impacted on DFS (p=0.010). Our results support the idea that MRD monitoring by MFC should be suggested before and 30 days after the transplant, while WT1 expression should be preferred after this procedure. The assessment of MRD at day +30 from allo-SCT is recommended as post transplant check-point for the predictive role displayed, independently of the method used.

    2015-11-01

    Bloodstream infection (BSI) is an important cause of morbidity and mortality in patients undergoing hematopoietic stem cell transplantation (HSCT). To evaluate the causative bacteria and identify risk factors for BSI associated mortality in febrile neutropenia patients undergoing HSCT, we collected the clinical and microbiological data from patients underwent HSCT between 2008 and 2014 and performed a retrospective analysis. Throughout the study period, among 348 episodes of neutropenic fever in patients underwent HSCT, 89 episodes in 85 patients had microbiological defined BSI with a total of 108 isolates. Gram-negative bacteria (GNB) were the most common isolates (76, 70.3%) followed by gram-positive bacteria (GPB, 29, 26.9%) and fungus (3, 2.8%). As to the drug resistance, 26 multiple drug resistance (MDR) isolates were identified. Resistant isolates (n = 23) were more common documented in GNB, mostly Escherichia coli (9/36, 25%) and Klebsiella pneumonia (6/24, 25%). A total of 12 isolated were resistant to carbapenem including 4 K pneumoniae (4/24, 16.7%), 3 Stenotrophomonas maltophilia, and 1 Pseudomonas aeruginosa and other 4 GNB isolates (Citrobacter freumdii, Pseudomonas stutzeri, Acinetobacter baumanii, and Chryseobacterium indologenes). As to the GPB, only 3 resistant isolates were documented including 2 methicillin-resistant isolates (Staphylococcus hominis and Arcanobacterium hemolysis) and 1 vancomycin-resistant Enterococcus faecium. Among these 85 patients with documented BSI, 11 patients died of BSI as primary or associated cause with a BSI-related mortality of 13.1 ± 3.7% and 90-day overall survival after transplantation at 80.0 ± 4.3%. Patients with high-risk disease undergoing allo-HSCT, prolonged neutropenia (≥15 days) and infection with carbapenem-resistant GNB were associated with BSI associated mortality in univariate and multivariate analyses. Our report revealed a prevalence of GNB in BSI of neutropenic patients undergoing

    Purpose: To evaluate survival and neurocognitive outcomes in pediatric acute lymphoblastic leukemia (ALL) patients with central nervous system (CNS) involvement treated according to an institutional protocol with stem cell transplantation (SCT) and a component of craniospinal irradiation (CSI) in addition to total-body irradiation (TBI) as preparative regimen. Methods and Materials: Forty-one pediatric ALL patients underwent SCT with TBI and received additional cranial irradiation or CSI because of CNS leukemic involvement. Prospective neurocognitive testing was performed before and after SCT in a subset of patients. Cox regression models were used to determine associations of patient and disease characteristics and treatment methods with outcomes. Results: All patients received a cranial radiation boost; median total cranial dose was 24 Gy. Eighteen patients (44%) received a spinal boost; median total spinal dose for these patients was 18 Gy. Five-year disease-free survival (DFS) for all patients was 67%. Those receiving CSI had a trend toward superior DFS compared with those receiving a cranial boost alone (hazard ratio 3.23, P=.14). Patients with isolated CNS disease before SCT had a trend toward superior DFS (hazard ratio 3.64, P=.11, 5-year DFS 74%) compared with those with combined CNS and bone marrow disease (5-year DFS 59%). Neurocognitive testing revealed a mean post-SCT overall intelligence quotient of 103.7 at 4.4 years. Relative deficiencies in processing speed and/or working memory were noted in 6 of 16 tested patients (38%). Pre- and post-SCT neurocognitive testing revealed no significant change in intelligence quotient (mean increase +4.7 points). At a mean of 12.5 years after transplant, 11 of 13 long-term survivors (85%) had completed at least some coursework at a 2- or 4-year college. Conclusion: The addition of CSI to TBI before SCT in pediatric ALL with CNS involvement is effective and well-tolerated. Craniospinal irradiation plus TBI is worthy

    Full Text Available Bacterial infections account for most infections in hematopoietic stem cell transplant recipients. While early mortality reduced dramatically with the introduction of the concept of empirical antibiotic therapy in neutropenic patients, no effect of prophylaxis on the mortality was observed in many studies. On the other hand, antibiotic prophylaxis has resulted in the emergence of resistance among bacteria. In addition, the choice of the antibiotic regimen for empirical therapy and the practices of antibiotic therapy during neutropenia may result in a significant shift in the pattern of bacterial infections. The use of quinolones and vancomycin as prophylaxis, and of carbapenems and vancomycin in the empirical antibiotic therapy, are associated with the appearance of resistant Gram-positive and Gram-negative bacteria. Therefore, hematologists must be aware of the impact of these practices on the emergence of infections due to multi-resistant pathogens, since these infections may be associated with increased mortality.

    2013-08-01

    While drug-related periostitis has been known of for many years, the specific association of diffuse periostitis with voriconazole (most frequently in transplant patients) has only been recently explicitly addressed in the literature. Recognition of the radiologic and clinical manifestations of voriconazole-related periostitis is important for helping to narrow an otherwise broad differential diagnosis. We present two cases that illustrate different radiologic presentations of this painful cause of diffuse periostitis. Case 1 features a 60 year-old woman with a history of orthotopic heart transplant who was hospitalized for "full body pain" with progressively worsening bone tenderness involving the humeri, knees, femurs, hips, and hands. Case 2 describes a 48 year-old man with a history of acute lymphoblastic leukemia status post stem cell transplant who presented with diffuse arthralgias involving bilateral ankles, knees, wrists, and elbows.

    Bioelectrical impedance analysis (BIA) is a method for the assessment of nutritional status. We studied the effect of graft function on nutritional status in postrenal 45 transplant patients with borderline to good allograft function using BIA. The patients had a mean serum creatinine of 1.42 ± 0.42 mg% and mean glomerular filtration rate (GFR) of 45.1 ± 14.1 mL/min. Based on BIA-derived GFR, the patients were divided into two groups; group 1: borderline graft function GFR nutritional status compared with those in group 2. Based on phase angle, there were significant differences between group A (phase angle 4.0) in extracellular water (P nutritional status, but when compared with healthy individuals as assessed by BIA, there were significant differences in FM, FFM, and body cell mass. In conclusion, BIA was more sensitive to evaluate nutritional depletion than SGA in transplant patients with borderline.

    Ischemic insults affecting the internal capsule result in sensory-motor disabilities which adversely affect the patient's life. Cerebral endothelial cells have been reported to exert a protective effect against brain damage, so the transplantation of healthy endothelial cells might have a beneficial effect on the outcome of ischemic brain damage. In this study, endothelin-1 (ET-1) was injected into the rat internal capsule to induce lacunar infarction. Seven days after ET-1 injection, microvascular endothelial cells (MVECs) were transplanted into the internal capsule. Meningeal cells or 0.2% bovine serum albumin-Hank's balanced salt solution were injected as controls. Two weeks later, the footprint test and histochemical analysis were performed. We found that MVEC transplantation improved the behavioral outcome based on recovery of hind-limb rotation angle (P<0.01) and induced remyelination (P<0.01) compared with the control groups. Also the inflammatory response was repressed by MVEC transplantation, judging from fewer ED-1-positive activated microglial cells in the MVEC-transplanted group than in the other groups. Elucidation of the mechanisms by which MVECs ameliorate ischemic damage of the white matter may provide important information for the development of effective therapies for white matter ischemia.

    Renal cancer occurs more frequently in renal transplanted patients than in the general population, affecting native kidneys in 90% of cases and the graft in 10 %. In addition to general risk factors, malignancy susceptibility may be influenced by immunosuppressive therapy, the use of calcineurin inhibitors (CNI) as compared with mammalian target of rapamycin inhibitors, and the length of dialysis treatment. Acquired cystic kidney disease may increase the risk for renal cancer after transplantation, while autosomal dominant polycystic kidney disease does not seem to predispose to cancer development. Annual ultrasound evaluation seems appropriate in patients with congenital or acquired cystic disease or even a single cyst in native kidneys, and every 2 years in patients older than 60 years if they were on dialysis for more than 5 years before transplantation. Immunosuppression should be lowered in patients who develop renal cancer, by reduction or withdrawal of CNI. Although more evidence is still needed, it seems reasonable to shift patients from CNI to everolimus or sirolimus if not already treated with one of these drugs, with due caution in subjects with chronic allograft nephropathy.

    Full Text Available Renal transplantation is the best method of renal replacement therapy for patients with end-stage renal disease. On the other hand in the early or late period of transplantation, majority of patients suffer from allograft failure and return to the dialysis. These patients carry the risks of adverse effects of previous immunosuppressive therapy (i.e infections and cancers. Furthermore, worse quality of life and many limitations of dialysis result in psychological problems. The controversial issues in treatment of these patients can be summarized under the headings of : 1- In which stage of allograft failure these patients should return to dialysis? 2- Which is the most appropriate renal replacement therapy after the renal allograft failure? 3- What are the main problems during dialysis practice and how should these problems be managed? 4- How should the immunosupression regimen be managed? 5- What are the indications for transplant nephrectomy? 6- What are the advantages and drawbacks of retransplantation? In this review these problems were discussed. [ Türkçe Özet ] [ PDF ] [ Benzer Makaleler

    The aim of the present study was to investigate the outcome of 94 adult patients with myelodysplasia (MDS) who received an allogeneic stem cell transplant between January 1995 and September 2010 in two Italian hematology centers. At the time of transplant, 53 patients (56%) had relapsed/refractory disease. The cumulative incidence of grades II-IV acute graft-versus-host disease (GVHD) and chronic GVHD was 33% (95% confidence interval [CI] 21-45%) and 78% (95% CI 66-90%), respectively. The cumulative incidence of transplant-related mortality (TRM) at 100 days was 13% (95% CI 6-21%). The 2-year progression free survival (PFS) and overall survival (OS) were 41% (95% CI 31-51%) and 49% (95% CI 38-59%), respectively. On multivariate analysis, advanced disease stage at transplant was the major independent variable associated with an inferior 2-year PFS (HR 3.66, 95% CI 1.98-6.76) and OS (HR 3.68, 95% CI 1.95-6.93). Use of an alternative donor was an independent variable associated with TRM (HR 3.18, 95% CI 1.31-7.72). In conclusion, our data suggest that disease status at the time of transplant is the major predictor for improved PFS and OS, and treatments required to reach this goal may have value in leading to an improved outcome.

    Bone marrow transplantation has been adoptively transferred from oncology to the treatment of autoimmune disorders. Along with extension of prevalent transplant-related concepts, the assumed mechanism that arrests autoimmunity involves elimination of pathogenic cells and resetting of immune homeostasis. Similar to graft versus tumor (GVT) reactivity, allogeneic transplants are considered to provide a better platform of immunomodulation to induce a graft versus autoimmunity reaction (GVA). It is yet unclear whether recurrence of autoimmunity in both autologous and allogeneic settings reflects relapse of the disease, transplant-associated immune dysfunction or insufficient immune modulation. Possible causes of disease recurrence include reactivation of residual host pathogenic cells and persistence of memory cells, genetic predisposition to autoimmunity and pro-inflammatory characteristics of the target tissues. Most important, there is little evidence that autoimmune disorders are indeed abrogated by current transplant procedures, despite reinstitution of both peripheral and thymic immune homeostasis. It is postulated that non-specific immunosuppressive therapy that precedes and accompanies current bone marrow transplant strategies is detrimental to the active immune process that restores self-tolerance. This proposition refocuses the need to develop strategies of immunomodulation without immunosuppression.

  13. Transplantation? Peripheral Stem Cell/Bone Marrow/Cord Blood

    2012-01-01

    Full Text Available The introduction of peripheral stem cell (PSC and cord blood (CB as an alternative to bone marrow (BM recently has caused important changes on hematopoietic stem cell transplantation (HSCT practice. According to the CIBMTR data, there has been a significant decrease in the use of bone marrow and increase in the use of PSC and CB as the stem cell source for HSCT performed during 1997–2006 period for patients under the age of 20. On the other hand, the stem cell source in 70% of the HSCT procedures performed for patients over the age of 20 was PSC and the second most preferred stem cell source was bone marrow. CB usage is very limited for the adult population. Primary disease, stage, age, time and urgency of transplantation, HLA match between the patient and the donor, stem cell quantity, and the experience of the transplantation center are some of the associated factors for the selection of the appropriate stem cell source. Unfortunately, there is no prospective randomized study aimed to facilitate the selection of the correct source between CB, PSC, and BM. In this paper, we would like to emphasize the data on stem cell selection in light of the current knowledge for patient populations according to their age and primary disease.

    Full Text Available Autologous stem cell transplantation (ASCT is a feasible procedure for human immunodeficiency virus-1 (HIV-1 lymphoma patients, whose underlying disease and intrinsic HIV-1- and ASCT-associated immunodeficiency might increase the risk for γ-herpesvirus load persistence and/or reactivation. We evaluated this hypothesis by investigating the levels of Epstein-Barr virus (EBV- and Kaposi sarcoma-associated herpesvirus (KSHV-DNA levels in the peripheral blood of 22 HIV-1-associated lymphoma patients during ASCT, highlighting their relationship with γ-herpesvirus lymphoma status, immunological parameters, and clinical events. EBV-DNA was detected in the pre-treatment plasma and peripheral blood mononuclear cells (PBMCs of 12 (median 12,135 copies/mL and 18 patients (median 417 copies/10(6 PBMCs, respectively; the values in the two compartments were correlated (r = 0.77, p = 0.0001. Only EBV-positive lymphomas showed detectable levels of plasma EBV-DNA. After debulking chemotherapy, plasma EBV-DNA was associated with lymphoma chemosensitivity (p = 0.03 and a significant higher mortality risk by multivariate Cox analysis adjusted for EBV-lymphoma status (HR, 10.46, 95% CI, 1.11-98.32, p = 0.04. After infusion, EBV-DNA was detectable in five EBV-positive lymphoma patients who died within six months. KSHV-DNA load was positive in only one patient, who died from primary effusion lymphoma. Fluctuations in levels of KSHV-DNA reflected the patient's therapy and evolution of his underlying lymphoma. Other γ-herpesvirus-associated malignancies, such as multicentric Castleman disease and Kaposi sarcoma, or end-organ complications after salvage treatment were not found. Overall, these findings suggest a prognostic and predictive value of EBV-DNA and KSHV-DNA, the monitoring of which could be a simple, complementary tool for the management of γ-herpesvirus-positive lymphomas in HIV-1 patients submitted to ASCT.

    Full Text Available OBJECTIVE: Post-transplant anemia is a common complication in renal allograft recipients. The most common causes are impaired graft function, immunosuppressive drugs, and infections. The aim of our study was to further investigate the prevalence of anemia before and after renal transplantation in renal allograft recipients in Turkey. MATERIAL and METHODS: We assessed 464 patients who received a kidney transplant between the years 2010 and 2012. The prevalence of anemia was evaluated before transplantation and at the 3 rd and at 6th months after transplantation. Our study is a retrospective study. RESULTS: The prevalence of anemia at the 6th month after the transplant surgery was 28.8%. The percentage of the patients who did not have anemia prior to the transplant surgery, and who developed anemia after the transplantation was 24.4%. CONCLUSION: Our findings are similar to those found in the literature, and show that anemia is a very common entity after renal transplantation.

    Early immune reconstitution plays a critical role in clinical outcome after allogeneic hematopoietic stem cell transplantation (HSCT). Natural killer (NK) cells are the first lymphocytes to recover after transplantation and are considered powerful effector cells in HSCT. We aimed to evaluate...... the clinical impact of early NK cell recovery in T cell-replete transplant recipients. Immune reconstitution was studied in 298 adult patients undergoing HSCT for acute myeloid leukemia, acute lymphoblastic leukemia, and myelodysplastic syndrome from 2005 to 2013. In multivariate analysis NK cell numbers...... on day 30 (NK30) > 150 cells/µL were independently associated with superior overall survival (hazard ratio, .79; 95% confidence interval, .66 to .95; P = .01). Cumulative incidence analyses showed that patients with NK30 > 150 cells/µL had significantly less transplant-related mortality (TRM), P = .01...

    The development of cell replacement techniques is promising as a potential treatment for photoreceptor loss. However, the limited integration ability of donor and recipient cells presents a challenge following transplantation. In the present study, retinal progenitor cells (RPCs) were harvested from the neural retinas of enhanced green fluorescent protein mice on postnatal day 1, and expanded in a neurobasal medium supplemented with fetal bovine serum without endothelial growth factor. Using a confocal microscope, immunohistochemistry demonstrated that expanded RPCs in vitro maintain retinal stem cell properties and can be differentiated into photoreceptor cells. Three weeks after transplantation, subretinal transplanted RPCs were found to have migrated and integrated into the outer nuclear layer of recipient retinas with laser injury, some of the integrated cells had differentiated into photoreceptors, and a subpopulation of these cells expressed photoreceptor specific synaptic protein, appearing to form synaptic connections with bipolar cells. These results suggest that subretinal transplantation of RPCs may provide a feasible therapeutic strategy for the loss of retinal photoreceptor cells.

    Mucormycoses remain a serious complication in patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT). In these patients, mortality rates of mucormycosis reach up to 90%, which is due, at least in part, to the severe and prolonged immunosuppression after transplantation. Although prolonged neutropaenia is one of the most important risk factors for mucormycosis, other cell populations, such as CD4(+) T cells may also provide critical defence mechanisms against this infection. The management of mucormycosis includes antifungal therapy, surgery and, most importantly, the control of the underlying predisposing conditions, such as the correction of an impaired immune system. Here, we review the current data of granulocytes, antifungal T cells and natural killer cells regarding their activity against mucormycetes and regarding a potential immunotherapeutic approach. It is hoped that further animal studies and clinical trials assessing immunotherapeutic strategies will ultimately improve the poor prognosis of allogeneic HSCT recipients suffering from mucormycosis.

    Studies applying exercise, relaxation training, and psychoeducation have each indicated a positive impact on physical performance and/or psychological factors in patients diagnosed with cancer. We explored the longitudinal effect of a combination of these interventions on treatment-related symptoms in patients undergoing myeloablative allogeneic hematopoietic stem cell transplantation (allo-HSCT). Forty-two patients (18-65 years) were randomized either to an intervention or a control group. The intervention group received standard treatment and care, and a supervised four- to six-week structured exercise program, progressive relaxation, and psychoeducation during hospitalization, one hour per day for five days per week. The control group received standard treatment, care, and physiotherapy. A 24-item symptom assessment questionnaire was completed weekly during hospitalization, and at three and six months after allo-HCST. Through principal component analysis with varimax rotation, individual symptoms were grouped into five symptom clusters: mucositis, cognitive, gastrointestinal, affective, and functional symptom clusters. Then, a subsequent general estimate equation analysis revealed similar longitudinal patterns of intensity in all symptom clusters for intervention and control groups, but in the intervention group, there was an overall significant reduction (P<0.05) in symptom intensity over time for all clusters except the affective symptom cluster. This study provides beginning evidence for the efficacy of an exercise-based multimodal intervention in reducing the intensity of a spectrum of symptoms in this small sample of patients undergoing allo-HSCT.

    Karyotype analysis in acute myeloid leukemia (AML) is one of the powerful prognostic factors for complete remission (CR), relapse, and overall survival (OS). Cytogenetic mosaicism is considered to be one of the important characteristics in expression of phenotypic manifestations. However, it has not come into focus due to emerging molecular biological approaches and the results of a number of mutation studies. Clinical correlates and prognostic relevance of mosaicism were evaluated in 163 AML patients [adverse-risk karyotypes (n = 72) and undefined karyotypes (n = 91)]. All patients were treated by induction and consolidation chemotherapies and finally went on hematopoietic stem cell transplantations (HSCT). Patients were divided into two subgroups, either with or without normal karyotype (NK) mosaicism. Seventy patients exhibited NK mosaicism and 93 did not. There were no significant differences in age, gender, chemotherapy cycles to achieve CR, HSCT donor type, source or intensity properties between the two subgroups. We found that NK mosaicism remaining in adverse-risk and undefined karyotype at diagnosis significantly correlates with better OS (p = 0.001) and lower CIR (p = 0.021) rate after HSCT. Our data show that the poor prognostic properties of unfavorable risk karyotype can be overcome to a great extent by allogeneic HSCT and chronic GVHD, especially in the subgroup with NK mosaicism. Cytogenetic mosaicism at initial diagnosis can be an influential factor for survival outcomes, even after HSCT.

    This study was aimed to investigate the prophylactic effect of CsA, MTX and MMF combined with ATG on graft versus host disease (GVHD) after unrelated donor peripheral blood hematopoietic stem cell transplantation (URD-PBHSCT). 33 patients underwent URD-PBHSCT with unrelated donor of HLA matched or 1 locus mismatched. The clinical data of all cases were retrospectively analyzed. URD-PBHSCT recipients received cyclosporin A+short term MTX+mycophenolate mofetil (MMF)+antithymocyte globulin to prevent GVHD (URD-ATG group), while 13 out of 33 patients were given additionally anti-CD25 antibody (URD-ATG+CD25 group). The results showed that engraftment was successfully achieved in 100% of all patients. In URD-ATG+CD25 group and URD-ATG group, the incidence of aGVHD were 23.07% and 45%, the incidence of cGVHD were 0 and 47.4% respectively. The latter was significantly higher than the former (pMMF+ATG as the prophylaxis of GVHD for UDR-PBSCT is effective. Reducing the dose of ATG may be good for patient in progression status.

    retiro del catéter de Hickman, se hace necesaria una patronización de cuidados relacionados a ese catéter, tanto para el equipo de salud como para el paciente y su cuidador.OBJECTIVE: To identify rationale for removal of the first Hickman catheter implanted in patients undergoing allogeneic hematopoietic stem cell transplantation, the micro-organisms involved in the occurrence of infection, and the length of time the catheter was in situ. METHODS: A cross sectional, retrospective study was conducted. The sample consisted of 57 transplant recipients. To conduct chart review, an instrument was developed containing variables related to patient identification, time of catheter use, reason for withdrawal, and isolated micro-organisms. RESULTS: Among the reasons for catheter removal, frequent infection (49% was the most common; the Stenotrophomonas maltophilia microorganism (25% was the most frequently isolated. CONCLUSIONS: Due to the high incidence of infectious complications leading to Hickman catheter removal, it is essential to standardize catheter care for the health care team, patients and their caregivers.

    Full Text Available Prince Mohan, Manish Kadian, Titte R Srinivas Division of Nephrology, Department of Medicine, Medical University of South Carolina, Charleston, SC, USA Abstract: Perhaps as a consequence of increased obesity in the general population, the likelihood of obese patients receiving kidney transplants has more than doubled. Obesity confers increased risk for graft loss and death among renal transplant recipients. However, the relationship of changes in body weight and composition to outcome on the transplant waitlist and posttransplantation are not straightforward. Strategies to manage weight in the waitlisted and post-kidney transplantation patient must be performed in the context of a multidisciplinary approach and individualized to risk factors in particular patients. While retrospective studies offer considerable insight into the relationship between obesity and kidney transplant outcome, causal inferences must be made with great caution.

    Full Text Available Abstract Background Diabetes is a disease of increasing worldwide prevalence and is the main cause of chronic renal failure. Type 1 diabetic patients with chronic renal failure have the following therapy options: kidney transplant from a living donor, pancreas after kidney transplant, simultaneous pancreas-kidney transplant, or awaiting a deceased donor kidney transplant. For type 2 diabetic patients, only kidney transplant from deceased or living donors are recommended. Patient survival after kidney transplant has been improving for all age ranges in comparison to the dialysis therapy. The main causes of mortality after transplant are cardiovascular and cerebrovascular events, infections and neoplasias. Five-year patient survival for type 2 diabetic patients is lower than the non-diabetics' because they are older and have higher body mass index on the occasion of the transplant and both pre- and posttransplant cardiovascular diseases prevalences. The increased postransplant cardiovascular mortality in these patients is attributed to the presence of well-known risk factors, such as insulin resistance, higher triglycerides values, lower HDL-cholesterol values, abnormalities in fibrinolysis and coagulation and endothelial dysfunction. In type 1 diabetic patients, simultaneous pancreas-kidney transplant is associated with lower prevalence of vascular diseases, including acute myocardial infarction, stroke and amputation in comparison to isolated kidney transplant and dialysis therapy. Conclusion Type 1 and 2 diabetic patients present higher survival rates after transplant in comparison to the dialysis therapy, although the prevalence of cardiovascular events and infectious complications remain higher than in the general population.

    TBI-based preparative regimens are considered as standard conditioning therapy for allogeneic stem cell transplantation (AHSC) in patients with ALL. We investigated toxicity and efficacy of a non-TBI-based regimen consisting of treosulfan, etoposide and cyclophosphamide for ALL within a prospective study. Major inclusion criteria were CR and non-eligibility for TBI. Fifty patients with a median age of 46.5 years (range, 18-64) were included. Donors were HLA-identical sibling (n=8), matched (n=42) or mismatched (n=10) unrelated. The toxicity was moderate, resulting in a cumulative incidence of non-relapse mortality (NRM) at 1 year of 8% (90% confidence interval: 2-15%). Acute GvHD grade II-IV and grade III/IV was noted in 53% and 14%, respectively. Chronic GvHD at one year was seen in 41%. After a median follow-up of 24 months the cumulative incidence of relapse was 36% (90% confidence interval: 24-48) and 51% (90% confidence interval: 37-65) at 1 and 2 years, respectively. The estimated 2-year disease-free and overall survivals were 36 and 48%, respectively. Treosulfan, etoposide and cyclophosphamide followed by AHSC has a favorable toxicity profile with low NRM and therefore represents a potential alternative regimen for ALL in 1. CR (NCT00682305).

    Full Text Available Hematopoietic cell transplantation (HCT is an accepted treatment for acute myeloid leukemia (AML in first remission, the treatment of choice for chronic myeloid leukemia (CML and high risk groups of ALL who relapse with conventional chemotherapy. We assessed results of HCT for pediatric leukemia in our center. A total of 92 children, 63 with diagnose of AML, 23 with ALL and 6 with CML received allogeneic transplantation from HLA full matched siblings (57.6% and autologous transplantation (42.4%. Source of hematopoietic cells were peripheral blood 83.7%, bone marrow 15.2% and cord blood 1.6%. The median transplanted nucleated cells were 6.4 ± 4.7 ×108 /Kg (body weight of patients and mononuclear cells were 5.5 ± 2.9×108/Kg. The most common conditioning regimens were cyclophosphamide + busulfan. Prophylaxis regimen for GVHD was cyclosporin ± methotrexate. GVHD occurred in 50 (54.3% patients. Eighty five of children had engraftment, 26 (28.6% relapsed and 57 (62% are alive. The most common cause of death was relapse (68.6%. Five years overall survival of patients with AML and ALL were 49% and 44% respectively and disease free survival of them were 52% and 49%. One year overall survival and disease free survival of CML was 57%. Overall survival increased with increasing age of patients at transplantation time (P = 0.06. Longer survival significantly related to earlier WBC and platelet recovery (P < 0.0001 and P = 0.006 respectively. Considering acceptable overall and disease free survival of patients after HCT, we concluded that is a good modality in treatment of leukemia of children.

    Full Text Available Preimplantation genetic diagnosis (PGD for HLA typing is steadily becoming an option for at risk couples with thalassemic children, requiring HLA matched bone marrow transplantation treatment. The paper presents the world’s largest PGD experience of 475 cases for over 2 dozens thalassemia mutations, resulting in birth of 132 unaffected children. A total of 146 cases were performed together with preimplantation HLA typing, resulting in detection and transfer of HLA matched unaffected embryos in 83 of them, yielding the birth of 16 HLA matched children, potential donors for their affected siblings. The presented experience of HLA matched stem cell transplantation for thalassemia, following PGD demonstrated a successful hematopoietic reconstitution both for younger and older patients. The data show that PGD is an efficient approach for HLA matched stem cell transplantation treatment for thalassemia.

    Thayna Nogueira dos Santos

    Full Text Available ABSTRACT The aim of the study was to investigate the association between oxidative stress and DNA damage with grafting time in patients submitted to autologous hematopoietic stem-cell transplantation (HSCT. The study included 37 patients submitted to autologous HSCT diagnosed with Multiple Myeloma (MM and lymphoma (Hodgkin’s and non-Hodgkin’s. Biomarkers of oxidative stress and DNA damage index (DI were performed at baseline (pre-CR of the disease and during the conditioning regimen (CR, one day after the HSCT, ten days after HSCT and twenty days after HSCT, as well as in the control group consisting of 30 healthy individuals. The outcomes showed that both groups of patients had an hyperoxidative state with high DI when compared to baseline and to the control group and that the CR exacerbated this condition. However, after the follow-up period of the study, this picture was re-established to the baseline levels of each pathology. The study patients with MM showed a mean grafting time of 10.75 days (8 to 13 days, with 10.15 days (8 to 15 days for the lymphoma patients. In patients with MM, there was a negative correlation between the grafting time and the basal levels of GPx (r = -0.54; p = 0.034, indicating that lower levels of this important enzyme are associated with a longer grafting time. For the DI, the correlation was a positive one (r = 0.529; p = 0.030. In the group with lymphoma, it was observed that the basal levels of NOx were positively correlated with grafting time (r = 0.4664, p = 0.032. The data indicate the potential of these biomarkers as predictors of toxicity and grafting time in patients with MM and Lymphomas submitted to autologous HSCT.

    Several gene mutations have been shown to provide clinical implications in patients with acute myeloid leukemia (AML). However, the prognostic impact of gene mutations in the context of allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains unclear. We retrospectively evaluated the clinical implications of 8 gene mutations in 325 adult AML patients; 100 of them received allo-HSCT and 225 did not. The genetic alterations analyzed included NPM1, FLT3-ITD, FLT3-TKD, CEBPA, RUNX1, RAS, MLL-PTD, and WT1. In patients who did not receive allo-HSCT, older age, higher WBC count, higher lactate dehydrogenase level, unfavorable karyotype, and RUNX1 mutation were significantly associated with poor overall survival (OS), while CEBPA double mutation (CEBPA(double-mut)) and NPM1(mut)/FLT3-ITD(neg) were associated with good outcome. However, in patients who received allo-HSCT, only refractory disease status at the time of HSCT and unfavorable karyotype were independent poor prognostic factors. Surprisingly, RUNX1 mutation was an independent good prognostic factor for OS in multivariate analysis. The prognostic impact of FLT3-ITD or NPM1(mut)/FLT3-ITD(neg) was lost in this group of patients receiving allo-HSCT, while CEBPA(double-mut) showed a trend to be a good prognostic factor. In conclusion, allo-HSCT can ameliorate the unfavorable influence of some poor-risk gene mutations in AML patients. Unexpectedly, the RUNX1 mutation showed a favorable prognostic impact in the context of allo-HSCT. These results need to be confirmed by further studies with more AML patients.

    To improve the antimyeloma effect of donor lymphocyte infusion (DLI) after allogeneic stem cell transplantation in multiple myeloma, we investigated in a phase 1/2 study the effect of low-dose thalidomide (100 mg) followed by DLI in 18 patients with progressive disease or residual disease and prior ineffective DLI after allografting. The overall response rate was 67%, including 22% complete remission. Major toxicity of thalidomide was weakness grade I/II (68%) and peripheral neuropathy grade I/II (28%). Only 2 patients experienced mild grade I acute graft versus host disease (aGvHD) of the skin, while no grades II to IV aGvHD was seen. De novo limited chronic GvHD (cGvHD) was seen in 2 patients (11%). The 2-year estimated overall and progression-free survival were 100% and 84%, respectively. Adoptive immunotherapy with low-dose thalidomide and DLI induces a strong antimyeloma effect with low incidence of graft versus host disease.

    Fragile X syndrome (FXS) is a congenital disorder caused by expansion of CGG trinucleotide repeat at the 5' end of the fragile X mental retardation gene 1 (FMR1) on the X chromosome that leads to chromosomal instability and diminished serum levels of fragile X mental retardation protein (FMRP). Afflicted individuals often have elongated features, marfanoid habitus, macroorchidism and intellectual impairment. Evolving literature suggests the condition may actually protect from malignancy while chromosomal instability would presumably elevate the risk. Increased sensitivity to ionizing radiation should also be predicted by unstable sites within the DNA. Interestingly, in this report, we detail a patient with FXS diagnosed with acute lymphoblastic leukemia treated with induction followed by subsequent cycles of hyper-CVAD (cyclophosphamide, vincristine, doxorubicin, dexamethasone) with a complete response who then was recommended to undergo peripheral stem cell transplantation. The patient underwent total body irradiation (TBI) as a component of his conditioning regimen and despite the concern of his clinicians, developed minimal acute toxicity and successful engraftment. The pertinent literature regarding irradiation of patients with FXS is also reviewed.

    Iron overload is considered to be associated with various complications in patients who undergo both allogeneic (allo) and autologous hematopoietic stem cell transplantation (HSCT). A total of 23 alloHSCT recipients who started deferasirox treatment due to hyperferritinemia (ferritin ≥1,000 ng/mL) were analyzed retrospectively. The demographic characteristics, data about deferasirox treatment, and history of phlebotomy were obtained from the patients' files. The reduction in posttreatment ferritin levels was found statistically significant compared with pretreatment ferritin levels in both def+phlebotomy and def+nonphlebotomy groups (p = 0.025 and 0.017, respectively). The liver enzymes, especially ALT and bilirubins, were significantly reduced after the treatment (p deferasirox treatment reduced pretreatment ferritin levels below the level of 1,000 ng/mL in a median period of 94 days, and these data were found to be statistically significant (p deferasirox was 94 days (72-122). The most common adverse effects were nausea and vomiting, which occurred in three of the patients (13%). In conclusion, our data suggest that oral deferasirox treatment may be used as a safe and effective alternative method for reducing iron overload in alloHSCT recipients, whether combined with or without phlebotomy.

In this prospective study we monitored alloHSCT recipients by dermoscopy in order to assess its utility as an alternative noninvasive tool to early diagnose acute GVHD. Methods. Thirteen consecutive patients who received alloHSCT were examined clinically and dermoscopically towards aGVHD [days 28 (±7, 56 (±7, and 100 (±7], as well as in each patient who developed cutaneous aGVHD diagnosed according to clinical criteria (Glucksberg scale. Results. Six patients (46% developed symptoms of cutaneous acute GVHD (grade 1, n=3; grade 2, n=3. Dermoscopic evaluation revealed pinkish or reddish background and well-visible, multiple thin telangiectasias. Conclusion. To our knowledge, this is the first report on the use of dermoscopy to evaluate skin involvement in the course of acute GVHD suggesting its role as a diagnostic tool in follow-up of GVHD, which can be also used before clinical symptoms occur.

    We previously compared outcomes after allogeneic peripheral-blood stem cell (PBSC) and bone marrow (BM) transplantation in 706 patients with leukemia. We obtained long-term follow up on 413 of 491 patients who were alive at the time of the initial report: 141 PBSC and 272 BM recipients. Chronic graft-versus-host disease (GVHD) was more frequent after PBSC compared to BM transplantation (RR 1.65, P transplantation for patients with advanced chronic myeloid leukemia (33% versus 25%) but lower for those in first chronic phase (41% versus 61%) due to higher rates of late transplant-related mortality. Leukemia-free survival was similar after PBSC and BM transplantation for acute leukemia. These data represent the early experience with PBSC grafts. Long-term outcomes in recipients of more recent transplants are required to better evaluate the role of PBSC grafts relative to BM transplantation.

    Patients who undergo autologous hematopoietic stem cell transplantation (aHCT) for treatment of a relapsed or refractory lymphoma are at risk of developing therapy related- myelodysplasia/acute myeloid leukemia (t-MDS/AML). Part of the risk likely resides in inherent interindividual differences in their DNA repair capacity (DRC), which is thought to influence the effect chemotherapeutic treatments have on the patient's stem cells prior to aHCT. Measuring DRC involves identifying small differences in repair proficiency among individuals. Initially, we investigated the cell model in healthy individuals (primary lymphocytes and/or lymphoblastoid cell lines) that would be appropriate to measure genetically determined DRC using host-cell reactivation assays. We present evidence that interindividual differences in DRC double-strand break repair (by non-homologous end-joining [NHEJ] or single-strand annealing [SSA]) are better preserved in non-induced primary lymphocytes. In contrast, lymphocytes induced to proliferate are required to assay base excision (BER) or nucleotide excision repair (NER). We established that both NHEJ and SSA DRCs in lymphocytes of healthy individuals were inversely correlated with the age of the donor, indicating that DSB repair in lymphocytes is likely not a constant feature but rather something that decreases with age (~0.37% NHEJ DRC/year). To investigate the predictive value of pre-aHCT DRC on outcome in patients, we then applied the optimized assays to the analysis of primary lymphocytes from lymphoma patients and found that individuals who later developed t-MDS/AML (cases) were indistinguishable in their DRC from controls who never developed t-MDS/AML. However, when DRC was investigated shortly after aHCT in the same individuals (21.6 months later on average), aHCT patients (both cases and controls) showed a significant decrease in DSB repair measurements. The average decrease of 6.9% in NHEJ DRC observed among aHCT patients was much higher

    Hematopoietic stem cell transplantation (HSCT) is an effective approach for the treatment of severe combined immunodeficiency (SCID). However, SCID is not a homogeneous disease, and the treatment required for successful transplantation varies significantly between SCID subtypes and the degree of HLA mismatch between the best available donor and the patient. Recent studies are beginning to more clearly define this heterogeneity and how outcomes may vary. With a more detailed understanding of SCID, new approaches can be developed to maximize immune reconstitution, while minimizing acute and long-term toxicities associated with chemotherapy conditioning.

    Full Text Available The development of malignancies after solid organ transplants is a well-known complication. Cancer is associated with significant consequences for the organ transplant patient. It is expected that cancer will surpass cardiovascular complications as the leading cause of death in transplant patients within the next few years. We report on a 36-year-old male patient who developed mixed germ-cell testicular tumor seven years after liver transplantation for alcoholic cirrhosis. He was treated with orchiectomy, retroperitoneal lymph node dissection and post-operative chemotherapy.

    @@ Psoriasis is a common disease with a prevalence of up to 2% in the world population.1 The pathophysiological mechanism of this inflammatory disease has not been determined although it is generally accepted to have a genetic predisposition and be T-cell mediated. The lymphocytes are the target of psoriatic therapeutic strategies. Therapy resolves psoriasis for a time, but induces some severe side effects. Some cases of severe psoriasis, treated with multiple therapeutic regimens for many years, developed leukemia.

    HIV and AIDS is one of the biggest challenges all over the world. There are an approximately 34 million people living with the virus, and a large number of them become infected each year. Although there are some antiviral drugs for HIV viral load reduction, they are not sufficient. There is no cure for AIDS. Nowadays natural resistance or immunity has absorbed attentions. Because in some HIV positive patients progression trend is slow or even they indicate resistance to AIDS. One of the most interesting approaches in this category is CCR5 gene. CCR5 is a main cc-chemokine co-receptor that facilitates HIV-1 entry to macrophage and CD4(+) T cells. To now, many polymorphisms have been known by CCR5 gene that produces a truncated protein with no function. So, HIV-1 could not entry to immune-cells and the body resistant to HIV/AIDS. Δ32/Δ32 and m303/m303 homozygotes are example of mutations that could create this resistance mechanism. There is a new treatment, such as Hematopoietic Stem Cell transplantation (HSCT) in Berlin and Boston patients for Δ32/Δ32 mutation. It could eliminate co-receptor antagonist and highly-active-anti retroviral therapy (HAART) drugs problems such as toxicity, low safety and side-effects. Now there, the aim of this hypothesis will be evaluation of a new mutation CCR5 m303/m303 as autologous HSCT. This novel hypothesis indicates that autologous HSCT for m303/m303 could be effective treatment for anyone HIV/AIDS affected patient worldwide.

    Full Text Available Mayer-Rokitansky-Küster-Hauser (MRKH is a rare syndrome characterized by congenital aplasia of the uterus and vagina. The most common procedure used for surgical reconstruction of the neovagina is the McIndoe vaginoplasty, which consists in creation of a vaginal canal covered with a full-thickness skin graft. Here we characterized the autologous in vitro cultured vaginal tissue proposed as alternative material in our developed modified McIndoe vaginoplasty in order to underlie its importance in autologous total vaginal replacement. To this aim human vaginal mucosa cells (HVMs were isolated from vaginal mucosa of patients affected by MRKH syndrome and characterized with respect to growth kinetics, morphology, PAS staining, and expression of specific epithelial markers by immunofluorescence, Western blot, and qRT-PCR analyses. The presence of specific epithelial markers along with the morphology and the presence of mucified cells demonstrated the epithelial nature of HMVs, important for an efficient epithelialization of the neovagina walls and for creating a functional vaginal cavity. Moreover, these cells presented characteristics of effective proliferation as demonstrated by growth kinetics assay. Therefore, the autologous in vitro cultured vaginal tissue might represent a highly promising and valid material for McIndoe vaginoplasty.
